Yes, and your explanation for the murder of a CCW citizen in Minnesota? He told the cop he had a gun, the gun was not out, nothing to suggest any resistance whatsoever, yet he was shot 4 times and murdered in front of his wife and child.
That is an excellent point.
I think it along with all the stories like these (remember that SWATing of the Marine a few years back) provides some evidence that the police [at least a non-insignificant portion] think of themselves as the unquestionable authority and want to make it known/felt. In the case you cite, the Citizen even being armed was a threat to his authority (under the same reasoning that gun-confiscators wish to take your guns), and in the marine's case it was so that they could shoot someone (see how they crowd into the doorway?).
OK, maybe there's one. One. Out of tens of thousands? Hundreds of thousands? Millions of encounters of CCWs with police without incident.
BTW: I am one of those statistics.
It's real simple: Follow police orders and you don't risk being shot.
