Good grief. SWAT teams in the US are utterly out of control. It's one thing to have resources for the relatively rare armed robbery/hostage/mass shooter situation, to
respond to an outbreak of violence; it's quite another to be using them for drug raids and other contexts where they initiate or are the sole cause of violence. This goes hand in hand with the confrontation-obsessed gun culture we have, in which a subset of gun owners dwell constantly on the omnipresent risks of crime and the need for elephant-grade stopping power, despite the clear long-term trend of falling crime.
The Cato institute has worked with journalist Radley Balko (who is the expert in this area) to produce a map of botched SWAT raids: http://www.cato.org/raidmap
I really see no other course for citizens other than to start attending public meetings and speaking up whenever public figures spout truisms about the safety of law enforcement officers being top priority. It's not top priority, that's why they get paid the big bucks - to put the safety of law-abiding citizens above their own.
