They (the authorities in charge of the police) let them shoot "warning shots"? Wow. I thought only idiots and people in movies did the whole "warning shot" thing. They probably shoot to "wound" instead of kill too....which would explain why they only hit 2 of the 4 bad guys they had to shoot at.

Not violent enough for you? 
I think the major qualm with warning-shots is that those bullets have to land somewhere...it's better a criminal gets hit than some kid walking down the street. Shooting to wound is essentially the same; trying to hit a guy's leg from 30 feet away with a handgun isn't impossible, but it's hardly easy, especially when you're not a sociopath and you're shaking because you could well be ending someone's life. You go for the biggest mass on a person's body, and the one that will be most likely to stop them: their torso.
