American gun culture has little to do with this case. Cops behave like this because behind door number one there could be a guy with an assault rifle ready to take them down. In 99% of the cases there isn't, but if you do 100 of these raids without taking risks, it becomes more likely than not that your own children will become orphans.
It's hypocritical to attack the cops that (literally) fight to stay alive without saying anything about the root cause.
