Here is the final opinion in Garcia, a Federal Tort Claims Act claim against an Isleta Pueblo tribal cop, who intervened to break up a fight at a wedding (or, in the words of the court, “Two Weddings and a Broken Jaw”): Garcia v. United States.
The court held after a two-day bench trial that the United States could be liable for the actions of an off-duty tribal cop under a 638 contract and the FTCA, but that the cop had not committed a tort.
