The phrase, “just doing my job” comes to mind. It seems that was enough to clear the officers that killed Mr. Christie. The below video is from a media in Tampa and (for once) does a good job of covering the story.
Maybe there would be an outrage over this case if it was such common practice. Even another cop testified that this was torture, the family states the man had mental issues and the government system protected its own. Sad, very sad – my condolences to the family.
