content: Biggest reason is "lack of pay" followed closely by "incorrect or lack of training." Third place is "using veterans as cops," which is a bad idea because many of them have PTSD (one of my friends has it) and the army is trained to treat everyone on the other team as a deadly combatant. This is NOT appropriate for civilian use (SWAT is the exception. Soldiers as SWAT can be a good idea). Norway and South Korean cops have a WAY different attitude and rules of engagement, and that boils down to a different mindset and different training. edit: the fact that most are overweight (so they're less likely to chase / touch and more likely to shoot) and on steroids surely doesn't help. The FBI actually released those reports lol.
