the gun handling by those two thugs is extremely professional. I hear they spent some money and had a couple marines trained in house clearing develope those scenes.
However, the extreme proficiency in gun handling didn't match the characters, a couple of do nothing punks who get money by visiting the local sperm bank?
I think guns should be part of the costume of a character, and gun handling should be the same. Don't give every character a Deagle just because it looks good, but in the same vein, don't give everyone a customized kimber 1911 either. A street thug should be carrying a black plastic 9, and shooting it sideways. We all know it is ineffective, but it fits. A poor guy who whips out a gun should be producing an old beat up snub nose revolver, not a glock, etc etc.
