Background
Charles Friend was arrested for domestic battery after his ex-girlfriend, Jacqueline Hathaway, reported injuries and alleged abuse. Although a jury later acquitted Friend, he sued the arresting officers and the City of Decatur under Section nineteen eighty-three, claiming the arrest lacked probable cause and violated the Fourth Amendment by occurring without a warrant in his mother’s home. The district court granted summary judgment for the defendants.
The court’s reasoning
The court reviewed the probable cause determination de novo, finding that the totality of facts known to the officers warranted a reasonable belief that Friend committed domestic battery. Hathaway’s statements to medical staff, officers, and her daughter were sufficient to establish probable cause, and her inconsistencies or recantations did not negate that standard. Regarding the warrantless arrest in the home, the court found that Friend and his mother consented to the officers’ entry and presence. The officers’ statement that they would ‘hash this out’ if Friend was innocent was a conditional promise, not an outright lie that would vitiate consent.
Once a reasonably credible witness informs an officer that a suspect has committed a crime, the police have probable cause to arrest the suspect.
Mustafa v. City of Chicago, 442 F.3d 544, 548 (7th Cir. 2006)
What it means going forward
The decision reinforces that probable cause is an objective standard based on the information available at the time of arrest, insulating officers from liability even when witnesses are inconsistent or the suspect is later acquitted. It also clarifies that conditional assurances of leniency do not automatically invalidate consent to entry in a home.
