What Makes an Arrest Unlawful?

A lawful arrest requires probable cause — a reasonable belief, based on specific facts and circumstances, that a person has committed or is committing a crime. Probable cause is more than a hunch and more than suspicion. It requires articulable facts that would lead a reasonable officer to conclude a crime has occurred. When that standard isn't met and an officer arrests someone anyway, the arrest is unlawful — regardless of what happens afterward.

Unlawful arrests happen more often than most people expect. They occur when officers misidentify someone, when they act on bad tips or stale information, when they arrest people for protected activity like filming police or refusing to answer questions, and when personal bias or retaliation drives the decision to arrest rather than legitimate law enforcement purpose. In Kentucky, you have the right to be free from these abuses — and when that right is violated, you have legal recourse.

Types of Unlawful Arrest Claims

Arrest Without Probable Cause

This is the most straightforward form of unlawful arrest. If an officer arrests you without any reasonable factual basis to believe you committed a crime, the arrest violates the Fourth Amendment. Evidence of what the officer actually knew at the time of the arrest — not what they discovered afterward — is what courts examine when evaluating probable cause. If the facts known to the officer at the moment of arrest didn't support it, the arrest was unlawful regardless of whether charges were later filed or dropped.

Retaliatory Arrest

The First Amendment protects your right to criticize police, record their activity in public, and refuse to answer their questions. When an officer arrests someone in retaliation for exercising those rights — using a minor or pretextual charge as cover — that is a constitutional violation. Retaliatory arrests are difficult to prove because officers can usually point to some technical basis for the arrest, but courts have recognized that even a technically valid arrest can be unlawful if the true motivation was to punish someone for protected speech or conduct.

Mistaken Identity and False Arrest

Arrests based on mistaken identity — wrong person, wrong description, warrant meant for someone else — cause serious harm to people who did nothing wrong. Being booked, fingerprinted, and held in a cell is a traumatic experience even when you're released quickly. When law enforcement fails to take basic steps to verify identity before making an arrest, and someone is wrongfully detained as a result, there is a strong basis for a civil rights claim.

Arrest for Protected Activity

Filming police in a public space is constitutionally protected. Peacefully protesting is constitutionally protected. Refusing to identify yourself in states where you have no legal obligation to do so is protected. Arrests that target people for engaging in these activities — dressed up as disorderly conduct, obstruction, or other catch-all charges — are among the most common forms of unlawful arrest, and they are among the most important to challenge.

Your Legal Options After an Unlawful Arrest

If you were unlawfully arrested in Louisville or anywhere in Kentucky, you have two primary paths for legal relief. The first is in the criminal case itself: an attorney can challenge the legality of the arrest, seek suppression of any evidence obtained as a result, and push for dismissal of charges that stem from an unlawful detention. The second is a civil rights lawsuit under 42 U.S.C. § 1983, which allows you to seek monetary damages from the officer and potentially the department for the constitutional violation.

Brandon Lawrence evaluates both dimensions of every unlawful arrest case. What happened during and after the arrest matters — but so does the full context: the officer's history, any available video footage, witness accounts, and the paperwork the officer filed to justify the arrest. These cases require a thorough factual investigation and a clear understanding of how Fourth Amendment doctrine applies to the specific circumstances. That's exactly the kind of work Brandon Lawrence does.
