PNR referred to this in the comments of an earlier post (about the Department of Education craziness in California) but it warrants its own space.
In brief, a local SWAT team in Pima County Arizona performed a forced entry on a house where lived a man, Jose Guerena, who was suspected of illegal drug activities. In the process of entering the house, the SWAT team fired 70 rounds of ammunition. Jose was killed. Many, many questions remain about what led up to the events and how the SWAT team conducted themselves during and after the course of the shooting.
Mike at Confederate Yankee has been following this situation with informed interest. He is former USAF and a former police officer well versed in SWAT tactics and police procedures in general. His analysis of what happened and is happening is well worth your time (and it will take some time).
