We issue "Raid jackets" to every Trooper and we are required to carry shield and ID at all times. Usually when we have plainclothes cops mixed in a crowd, we teach them to yell the year we were founded. Had a big fight at UCONN one night and there were actually three departments undercovers mixed up in it, all of them yelling years the department was founded. During the briefing
( I was in uniform) we were told of the three years to listen for and I looked at my partner and said "Ok, don't OC spray anybody yelling ANY year."
