Roscoe, I'm going one more bold, daring and totally unsupportable and ill conceived prediction here ... I will predict that the officers had full legal basis to enter Zito's domain. It is possible from his behaviour before and after, that Zito was in the throes of an unresponsive and violent psychotic episode. If so, every rental agreement has a clause where the owner/manager and emergency/police personnel can enter a residency if for good cause. Not only that, but police can enter a home if they judge that a person within is imminently vulnerable to hurting themselves or someone else.
I'm going to say, they entered Zito's trailer with legal right and performing their duty vailiently. These two policemen did not finish lunch and say ... "ok partner, where to? Hey, let's go f*** with Zito." They were doing their job, they weren't Nazis or jackboots.
If so, if so, it was just two poor cops taking some lead but boy did the Freepers enjoy the hysteria of describing and loathing a new conjured police state.
Or, I could be wrong.
The officers died serving the public, yet lowlifes will try to defile their memories.
