Please hear me out because I am NOT defending the guy, but...
Police have to deal with scum pretty much all the time. Being taunted, abused, punched and kicked etc, while being expected to remain totally non-violent themselves throughout.
I'm not defending the guy, but what I'm saying is that I'm surprised you don't hear more stories of Police brutality. If you pulled over a drunk driver who was doing 80mph in a 30 zone with schools etc, are you telling me you honestly wouldn't be tempted to give the c*** a dig in the ribs? I'm very impressed by the restraint of coppers in most of these instances.
I agree as well - how would any of us want to deal with someone violent and struggling. I think a community sentence is right. Most of our police put up with such aggression on a daily basis and show enormous restraint. The fact that this guy didn't shouldn't mean he is sacked, but given a warning.
