point is,cops are people,like anyone else,they will try and have the best outcome for their case wheheter or not they are guilty . Holding a cop tthe same standards as civilians in every case is ridiculous as they are involved in with so many people whom are aggressive.....by the law of averages,at some point they will make a mistake. Take the case of the mentally challenged man, if it were a civilian facing him whom also had a two inch pocket knife,and said civilian slashed Mr.Minty and he died.Then the civilian would be let off as one is allowed to use euqal force to protect oneself in any case of violence. I certainly don't think the cop was justified in shooting him in the chest,but, if he would've shot him in the leg,that would have been appropriate,buit, he could of hit a femoral attery and killed him just the same. If we are to hold all police to such strict standards in protecting themselves and the community, you'd would for sure see an increase in violence. Cops must be able to be seen as having a difficult role and at times,it ends up with bad results. If you charged cops everytime the messed up,guess what,how many cops do you'd think we'd have?
