I had something similar happen to me in CA.
Two drunk off-duty officers assulted me in a public park for sitting on the wrong bench. (They wanted it for their drunk party)
One guy jumped over the table and came at me.
This happened nearly 15 years ago so its not a new thing.
This happened some years ago in St. Charles, Missouri (across the Missouri River from the St. Louis area): a drunk, off-duty cop picked a fight with a civilian in a bar, and the civilian took him up on the offer and punched him. Cop fell backwards and hit the back of his head when he landed. Cop died. Civilian went to prison for many years for killing a cop. True story. Moral of the story: cops are a protected and highly prized species, even when they’re trying to hurt or kill you - on duty or off.
