We hold badges accountable.
Kosloski Law is a Colorado civil rights and criminal defense firm. When police or the government violate someone's rights, Jason Kosloski, a former public defender, takes the fight to court.
The record shows what happened.
When an officer, a sheriff's deputy or a jail crosses the line, the first thing that goes missing is the truth. We bring it back into the record, in federal and state court.
Kosloski Law is a Colorado civil rights and police misconduct firm: excessive force, wrongful arrest, unlawful searches, jail medical neglect, wrongful death and First Amendment retaliation. The firm also defends people accused of crimes in Colorado.
Jason Kosloski spent years as a public defender trying cases against the government. He founded the firm to do the same work from the other side of the lawsuit. The firm calls itself trial-first: every case is prepared as if it will be tried.

Case files.
The kinds of matters the firm handles. Whether a particular situation fits is something only Jason can say after he reviews it himself.
Excessive force
When police use more force than the situation calls for, it can violate the Fourth Amendment. The firm holds officers and agencies accountable for excessive and deadly force.
FILE / FEES
Civil rights cases are taken on contingency: nothing upfront, and the firm is paid only if there is a recovery. Jason explains costs and fees in writing before anyone signs.

The call comes at 2 a.m. Casey picks up.
Not just a website: an AI assistant for the firm's phone and chat. Casey answers any hour, in English and Spanish, explains what the firm handles, takes a short conflict-check intake and holds a free consultation for Jason. He never gives legal advice, never says whether you have a case, and never quotes a fee. He is named for Casimiro Barela, the Colorado statesman who got the state constitution published in Spanish.
