State police or FBI might look into whether police broke the laws.
"Might", but won't.
"There were so many of us'
"We were doing what we were ordered to do"
"I just do as I'm told"
"Im not sure who was in charge"
All responsibility is diffused so far that "nobody" is really responsible any more.
And... nobody in a position to investigate really cares. Think that the FBI cares? They never put Lon Horiuchi in prison for shooting the face off of an unarmed woman who was not in a position to harm anyone... they sent him to Waco so he could shoot more people. The bottom line... hate to say it... is that there is no adult supervision of law enforcement that has any credibility any longer. The police get the result they want, and there's nothing at all legally available to stop it.
