Or stalked and attacked someone for noticing him acting suspiciously. There is at least as much evidence for the that as for the version his supporters promulgated.
A police officer is negligent in his duty if he allows an assault suspect to flee. And Brown was not shot while fleeing, as his own family's autopsy proved, unless he decided to flee facing the cop.
No, it is disregard for aesthetics and emotions, which are not supposed to have anything to do with the law and its application. By the nature of their job and duties, cops cannot say "Oops," and back off in such situations. What possible good could have come of not restraining the father? At best, you'd have someone running around screaming and yelling at a crime scene. At worst, it ends with him and maybe more people dead.

By the nature of the job, a cop can't back off in such a case, anymore than a bullet can crawl back into the gun barrel.

There is that. On the other hand, they'd find ways to not kick down doors, if they knew it was a no win situation.
Why would they rob a donut shop? Those places fawn on and cater to cops. I know cops who refuse to go into Dunkin' Donuts in uniform because they can't get them to take money. I also know cops who have refused to pay for coffee when asked by the clerk at a local convenience store.
Yeah, I'd bet every department has at least one of those.
I keep coming back to the line in Terry Pratchett's "Jingo" where Sam Vimes, the police chief, in a conference about a sudden military issue that has arisen, in response to condescending remark about "civilians" says something like "A police officer IS a civilian, that's the point." Why do cops need more powers than mall cops? I agree with letting cops carry guns, but only because I agree with anyone carrying guns. Including some retarded people and felons (which, come to think of it, is not all that different from many cops I know). But last week, I was down the shore and noticed all the Class I & II special officers who were doing the bulk of the patrolling on the boardwalk at Seaside. In NJ a Class I can't even carry a gun, and a Class II is very limited in his jurisdiction, not being allowed to do much more than issue citations under title 39 (which is the motor vehicle code - so basically, he can write tickets). If such officers suffice to safeguard the facility which is pretty much the sine qua non of the local economy, and the most crowded and busy place on the Barnegat Peninsula, with the lowest class element of humanity, why do the rest of us need tactical operatives, who are armed like soldiers, without the discipline, training or command structure of soldiers?
The literal definition of irresponsibilityYou would think.
