America is very large, and within it there are disparate groups with very different opinions on the level of force required by police. Sometimes I think that America would be better off if it weren't so large. Then there might be more of a consensus on this kind of thing. As it is, there are just too many different levels of government (local, state, federal) and people with all kinds of backgrounds and viewpoints setting up these enforcement bodies (for example, FBI is federal, there are likely to be many people from out-of-state in that enforcement branch, also, those SWAT police officers were probably trained out-of-state, just a guess on that though).
