How's that again?

"It's just tragic, that based on the guns that are on the streets, that three young men have lost their lives today," Chicago Police Supt. Jody Weis said.

I defy anyone to parse that sentence for linear logic. 

I suppose he meant "because of" rather than "based on." It would be just as bone-headed, but at least it would illustrate that Chief Jody is up to the demands of constructing a simple declarative sentence.
