I bet the SWAT guys went barrelling in there to be tough guys and blow away the cop killer, which is why two more of them died. No way should they have tried to force that situation against somebody like that -- you back out and use tear gas and the like until he surrenders. But that macho mentality won out, and two cops lost as a result. My brother commands the SWAT unit of a nearby city to Oakland (where we grew up), and I'm wondering what he has to say about this. It'll be interesting to hear him -- he's become something of an autonomic wingnut on lots of things in his time on the force, but he's still a smart, professional guy, and he remembers Oakland, and race relations, pretty well. There are lots of segments of Oakland where people see nothing wrong with killing cops, and the SWAT guys' apparent lack of professionalism here will only reinforce that mentality, despite the unfortunate deaths of those four men at the hands of a scumbag.
* My brother tells me he isn't sure if the SWAT guys knew he was in there -- they might have been breaking in to search the place on a tip, not knowing for sure if the guy was there at all. In that case, they were doing about the best they could. Jumping to conclusions on my part. He knows some of the Oakland SWAT guys, and is going to find out for sure, but if they did know the guy was in there, his basic take is similar to mine, although he won't say that in so many words.
