He didnt, she lied, he was also stopped because he fit the description of a convenience store robber from the day before. She lied and five cops died.
Who lied?
She lied about being stopped for a broken tail light, she may have driven the get away car in the robbery too. The dead guy was wearing the same clothes seen in the video of the robbery.
Seriously? This has been debunked two days ago.
