I generally frown upon assault, but I wouldn't automatically assume the officer wasn't getting a well-deserved ass whooping.
Nobody is supposed to beat on cops.
respectfully no I would not .. the amount of lawsuits I could face if my judgement was incorrect would over come my desire to help. I would sit and watch and say to myself "this is why i'm not a cop" as they were beat to death … however if a helpless citizen was being attacked of course I would help out, even if the attackers were" police".
I am no big strong person. so I wouldn't get into it. I would call 911 and let them do what needed to be done.
