From the PDF report of one of the officers involved, when asked about how he was identified:
"Uh, on my vest I have a, uh, circular patch that says Sheriff on it. Um, I think on my back I have Uh, a Sheriff patch.... (etc)."
Lest we forget, there have been articles posted here at FR and other places in the last couple of weeks that the Cartels members are wearing police uniforms quite regularly.

Of course 0bama, and his co-conspirators want it that way. They want warfare between the enforcers and the civilians. It will help them shut down the Constitution completely.

This is a very distressing event, even if the SWAT team did everything 'right' and even if it turns out that Guerena was as dirty and dangerous as they claim. I hate to see stuff like this, because I appreciate the tough and dangerous job that police officers do, and like pretty much all of the ones I am acquainted with and /or have met in the performance of their duties. But I also have a lot of love for freedom and the concept of innocent until proven guilty in a court of law.
