Mbe's for the officers.
If some scum bag violently attacked one of my female colleagues IAM sure a kicking would be appropriate.
Police officers are not meant to deal out punishment on the spot.
If anything they've possibly just done something that could weaken any case in court against the suspect, opened the force up to a case for excessive force - and stomping and kicking a contained suspect IS excessive and potentially lethal.
The guy should probably be locked up for a long time for what he did to the police, but the officer went massively over the top and has basically put every previous and future use of force he has done/will do in question as if he's willing/capable of giving someone a kicking very much in public it means that his actions out of the public eye are going to be questioned.
We expect and require our police to act professionally (and that does not include meting out "justice" with a size 13 boot), as when they fail to do that you're heading back to the bad old days when some units in the police were little more than uniformed thugs and there were questions over the safety of major cases due to misconduct.
I'm not quite old enough to "remember the good old days" when your local copper got away with giving people a beating, but I am old enough to remember the high profile cases where those "good old style coppers" messed up and got the wrong person, leaving the actual dangerous criminals to continue being a threat to society.
And before anyone says "he's soft" or "he's a lefty" I'm not. I'm someone what wants police to act professionally, if just because it means when cases get to court they're more likely to succeed and less likely to be thrown out, or have a conviction overthrown due to misconduct of the officers.
