check your newspaper for stories. particularly in the local section. Some good stories have been written from these kinds of ideas.
I read an article last week about a local shooting. It happened at a small community cookout. A drug deal gone awry. When cops arrived , one man was slumped over on the picnic table near the smoldering grill with a gunshot wound. He was barely breathing. The shooter was yelling at his gorlfriend. "See what you made me do? I just killed a man!" He said. He had a handgun tucked in his waistband. The cops told him to drop it...but he got inot that stance...hands out by his sides...the shifty eyes...he was ready to draw. He had nothing to live for now.

So, he iether draws, and the cops fire fifty round into him and the surrounding cars and buildings...

Or he chickens out and tosses the gun on the ground...and then they shoot him and beat him...

Or he takes the girl hostage, steals a police car...and they are both shot to death ten miles down the road as he crashes a roadblock...

Or, just make something up....
