Comments about ‘FBI opens investigation into Denver police beating’

So why isn't the FBI investigating the Martin/Zimmerman debacle in Florida? Why is the DOJ taking over the job of the FBI and prosecuting an already released innocent defendant in a self defense trial?

I think the FBI is being unjust in their actions in doing what it is supposed to do, investigate federal crimes of improper police and DOJ government actions? Or is the DOJ and off limits agency to the laws of this country and its constitution?

Then what about law enforcement departments that have declared they will not enforce local and federal laws to suit their special interests? Like the cities and state government of Utah that refuses to detain or investigate crimes of foreign occupation and intentional criminal theft and looting and pilfering actions by foreign nationals?

Where is the real Law and Order in this country? Has law and order been given the right and entitlement of the president to invoke/revoke or are laws of the land still in the hands of citizens?
