Want to know how to get a gun?

Just ask Chris.

The skinny teen attends high school in Chicago and is a talented athlete. But he’s also a notorious gunslinger.

As a shooter in a South Side gang, he can get his hands on a gun as quick as you can get a burger at a fast-food restaurant.

“I will make a call and say I need a gun. I will ride down the street on my bike and get it — five minutes.”

The Chicago Sun-Times sat down with Chris for a lesson on how gangs get guns. Armed gangs like Chris’ have driven up Chicago’s murder total 28 percent above the rate at this time last year. And Chris is on the front lines of the shooting. . .
