Robin:  Civility is a reasonable expectation of all of us in the community, I hope no one is saying otherwise.  However, I've learned over my 73 years that expectations, no matter how reasonable, are not always met.  

Mr. Bumpas was being a real "jerk." I haven't read anyone saying otherwise.  He was under arrest for being a jerk and he continued to be one after his arrest.  "Drunk and disorderly" are often paired  He was in the process of facing the legal consequences of such behavior.....receiving the community's "negative sanctions for behavior outside the normative order of the community." 

Officer Sharlow was in a very important and powerful position.  He misused that power in an egregious fashion and is facing the consequences of that action. No one, to my knowledge, has suggested, as you sarcastically put it, that we "just get rid of the police."  I will, however, suggest that it's not unreasonable to expect more civil behavior from police officers than from those they arrest.
