I went to a riot once 50-75 drunks fighting in a parking lot) while working In confinement and the uniform was short sleeve blues with tie
Had a big burly black dude reach out and grab my tie & when it popped off he was really surprised & that made it easy to get him in a arm bar & flat on his face
