Agree.
It depends what information the police had (albeit wrong info at the time), which is something we don't know. If the info was that this was a akin to a felony stop, then they were likely following their protocols, since in a felony stop, the last thing you want to do is approach a vehicle/boat/aircraft without being at the ready, then getting shot by a suspect.
Joe Gremlin, I can understand you not liking a personal aspect of it by describing what if you had to see your wife, yada, yada; but these things happen. No one got hurt, and now someone is going to have to be accountable for why this screwup happened. And rightfully so. But that screwup isn't with the on-scene officers who were simply acting on the bad info given to them from another agency.
