The United States has had a high level of gun ownership for several hundred years. The police response of "respond to anonymous tip by kicking down the door and opening fire" seems to be a mostly post-9/11 thing.
I suspect that the root causes are multifold:
(1) No-knock warrants became legal in 1995 to prevent the "destruction of evidence" during drug busts.
(2) Americans got really paranoid after 9/11, and more tolerant of this sort of police activity.
(3) Increasingly harsh prison conditions and unfair sentencing encourages suspects to fight back, rather than comply with law enforcement.
(4) We have a number of well-funded and well-trained paramilitary criminal organizations in the United States, thanks largely to the War on Drugs and decades of poorly-thought-out immigration policy.
