When the government’s case rests on evidence obtained through an illegal search, seizure, stop, or interrogation, Attorney Michael J. Petro moves to exclude that evidence from the record.

If federal agents or police violated the Fourth or Fifth Amendment, Attorney Michael J. Petro attacks the stop, search, seizure, warrant, or interrogation and asks the court to suppress the evidence.

A successful motion to suppress can change the entire direction of a federal criminal case. Drugs, firearms, statements, electronic evidence, financial records, or other evidence the government expected to use may be excluded from trial.

Federal Criminal Defense Attorney Michael J. Petro has extensive experience challenging unconstitutional police conduct and litigating motions to suppress evidence. He examines what officers actually did, compares their claims against the video, reports, warrants, recordings, and physical evidence, and forces the government to justify the search in court.

If the government’s case began with a questionable stop, search, warrant, seizure, or interrogation, do not assume the evidence is admissible. Contact Attorney Petro and have the search challenged.

Challenge the Government’s Evidence Before It Controls the Case

An evidence suppression motion is the first opportunity to attack the prosecution’s case.

Federal agents and police must follow constitutional limits when they stop a vehicle, enter a home, search a phone, seize a computer, execute a warrant, or interrogate a suspect.

When they cross those limits, Attorney Petro fights to keep the resulting evidence out of court.

He looks beyond the police report and asks:

  • Did officers actually have reasonable suspicion for the stop?
  • Was there probable cause for the search?
  • Did the warrant affidavit tell the whole truth?
  • Did officers search beyond what the warrant permitted?
  • Was consent truly voluntary?
  • Was a detention unlawfully prolonged?
  • Did officers interrogate the defendant after the defendant invoked the right to counsel or silence?
  • Did the government obtain later evidence because of an earlier constitutional violation?

The government has lawyers defending the search. You need a lawyer attacking it.

Illegal Traffic Stops

Many federal criminal cases begin with what appears to be an ordinary traffic stop.

Police may claim a driver was speeding, committed a lane violation, failed to signal, had an equipment violation, or violated some other traffic law. What matters is whether the officer actually had a lawful basis to make the stop.

Attorney Petro examines the evidence behind the officer’s justification, including:

  • Dash camera footage
  • Body camera footage
  • Radar or speed measurement evidence
  • Dispatch records
  • Officer reports
  • Traffic statutes
  • Timing and location
  • Statements made at the scene
  • The officer’s testimony

He also examines whether officers turned a legitimate traffic stop into an unconstitutional drug or firearm investigation by extending the detention beyond the time necessary to deal with the traffic violation.

If the stop was unlawful, evidence discovered because of it may be subject to suppression.

Fight Illegal Vehicle Searches

Being stopped does not give police unlimited authority to search your vehicle.

Officers may attempt to justify a vehicle search by claiming consent, probable cause, plain view, an inventory search, a search incident to arrest, or the automobile exception.

Attorney Petro does not simply accept the label officers place on the search. He examines whether the facts actually satisfy the legal requirements.

That means asking:

  • What did the officer supposedly see or smell?
  • Was consent actually given?
  • What exactly did the driver agree to?
  • Did officers exceed the scope of consent?
  • Was there really probable cause?
  • Was the vehicle actually being inventoried?
  • Did officers follow established inventory procedures?
  • Did the claimed justification arise only after officers had already begun searching?

A police officer cannot make an unconstitutional search lawful simply by describing it differently in a report.

Attack Defective Search Warrants

A judge signing a warrant does not make that warrant immune from challenge.

Federal search warrants frequently become the centerpiece of prosecutions involving drugs, firearms, fraud, electronic evidence, financial crimes, and other federal offenses.

Attorney Petro examines the warrant and the supporting affidavit line by line.

Potential challenges include:

  • Lack of probable cause
  • Stale information
  • Unsupported informant allegations
  • Material false statements
  • Material omissions
  • Failure to connect alleged criminal activity to the place searched
  • Overbroad warrants
  • Lack of particularity
  • Searches beyond the scope of the warrant
  • Improper execution of the warrant

Attorney Petro regularly litigates these issues as part of his searhttps://www.mjpetro.com/federal-motion-to-suppress-evidence-granted/ch and seizure practice.

The government starts with the warrant. The defense starts with whether the warrant should ever have been issued.

False or Misleading Warrant Affidavits

Police officers and federal agents do not get a free pass to obtain a warrant by presenting false or materially misleading information.

When the evidence supports it, the defense can challenge material false statements or omissions in a warrant affidavit.

Attorney Petro compares the affidavit against the underlying evidence, including:

  • Police reports
  • Recorded interviews
  • Surveillance
  • Body camera footage
  • Informant information
  • Electronic records
  • Witness statements
  • Other investigative materials

If the affidavit materially distorted the facts necessary to establish probable cause, the warrant’s validity can become a major issue in the case.

Police often defend a warrantless search by saying, “He consented.”

That does not end the inquiry.

Consent must be voluntary, and the government must justify the search based on the actual circumstances.

Attorney Petro examines who allegedly consented, what was said, whether the person had authority to consent, whether the police used coercion, and whether officers searched beyond the scope of any permission actually given.

A person agreeing to one limited request does not necessarily authorize officers to search everything they can find.

Protect the Home

The home receives some of the strongest protection under the Fourth Amendment.

Law enforcement cannot simply enter a residence because officers believe evidence may be inside.

Attorney Petro challenges unlawful residential searches involving:

  • Invalid warrants
  • Forced entry
  • Alleged consent
  • Claimed emergencies
  • Searches beyond the authorized area
  • Seizure of items outside the warrant
  • Questionable protective sweeps
  • Searches of containers, rooms, or electronic devices beyond the permitted scope

When agents search a home, every step of that search should be examined.

Challenge Cell Phone and Computer Searches

Federal prosecutions increasingly depend on digital evidence.

Phones and computers can reveal years of communications, photographs, financial information, location data, internet activity, and personal records. That does not give the government unlimited authority to search them.

Attorney Petro challenges digital searches involving:

  • Overbroad warrants
  • Lack of probable cause
  • Insufficient particularity
  • Searches outside the warrant’s scope
  • Unlawful seizure of devices
  • Excessive delays in obtaining or executing warrants
  • Searches of unrelated files or accounts

Digital evidence can decide a case. The defense should not assume the government obtained it lawfully.

Suppress Unlawfully Obtained Statements

The government’s evidence may include the defendant’s own words.

Attorney Petro examines whether federal agents or police violated constitutional protections while obtaining a statement.

Important questions include:

  • Was the defendant in custody?
  • Were Miranda warnings required?
  • Were the warnings properly given?
  • Did the defendant invoke the right to remain silent?
  • Did the defendant request an attorney?
  • Did officers continue questioning anyway?
  • Was the statement voluntary?
  • Did police use unlawful pressure or coercion?

An incriminating statement can be powerful evidence. That makes challenging the circumstances under which it was obtained especially important.

Attack Illegal Detentions and Arrests

Police cannot detain or arrest someone simply because they have a hunch.

An investigative detention requires legal justification. An arrest requires probable cause.

Attorney Petro examines what officers knew before they acted, not what they discovered afterward.

He challenges detentions and arrests where officers lacked sufficient facts, improperly prolonged a detention, escalated a stop without justification, or attempted to justify their actions based on evidence discovered only after the seizure occurred.

The government cannot use the evidence it found afterward to retroactively justify what police did beforehand.

Fight the Government at the Suppression Hearing

When a motion to suppress results in an evidentiary hearing, police officers and federal agents may have to take the witness stand and explain what they did.

That creates an opportunity to test their version of events through cross-examination.

Attorney Petro compares testimony against:

  • Body camera recordings
  • Dash camera recordings
  • Reports
  • Dispatch records
  • Search warrant affidavits
  • Photographs
  • Electronic records
  • Prior statements
  • Physical evidence

Inconsistencies matter.

What an officer says months later in court can be very different from what the video, report, or contemporaneous evidence actually shows.

Attorney Petro prepares suppression hearings to expose those differences and force the government to prove that its evidence was obtained lawfully.

Suppression issues should be investigated early.

Attorney Petro represents clients in federal investigations and grand jury proceedings and begins evaluating search-and-seizure issues as soon as evidence becomes available.

Waiting can matter.

Video can disappear. Memories can fade. Records may become harder to obtain. A defendant can also make major decisions about cooperation or a plea before understanding that critical government evidence may be vulnerable to suppression.

The defense should understand the strength of the suppression issue before making decisions that could permanently affect the case.

A Suppression Motion Can Change Plea Negotiations

The strength of the government’s evidence drives plea negotiations.

If critical evidence is vulnerable to suppression, the government’s leverage may change dramatically.

Attorney Petro evaluates suppression issues before advising clients about federal plea negotiations.

A defendant should understand whether the government’s evidence can be challenged before giving up constitutional rights and entering a guilty plea.

Suppression Can Change a Federal Trial

The government must prove its case with admissible evidence.

If unlawfully obtained drugs, firearms, electronic evidence, statements, financial records, or other evidence are excluded, prosecutors may be forced to proceed with a very different case.

Attorney Petro prepares for federal criminal trials by challenging the government’s evidence before the jury ever sees it.

A successful suppression ruling does not automatically dismiss every case. But when the suppressed evidence is central to the prosecution, the consequences can be substantial.

Preserve Suppression Issues for Federal Appeal

An adverse suppression ruling may also present an important appellate issue.

Attorney Petro represents clients in federal criminal appeals involving search warrants, probable cause, traffic stops, consent searches, Fourth Amendment violations, and other preserved constitutional issues.

That makes it important to develop the factual record and legal arguments correctly in the district court.

Attorney Michael J. Petro Challenges Illegal Government Searches

The government will defend its agents and officers.

Your defense should challenge them.

Attorney Petro reviews the reports, obtains the video, examines the warrant, studies the timeline, tests the officer’s justification, and identifies constitutional violations that may prevent the government from using its evidence.

His representation can include:

Fight the Search. Fight the Evidence. Fight the Case.

If the government found drugs, guns, electronic evidence, documents, money, statements, or other evidence after stopping, searching, detaining, or interrogating you, do not assume that evidence can be used against you.

The legality of the government’s conduct should be investigated before you make decisions about a plea, cooperation, or trial.
