Justin Bieber's DUI case-video footage, capturing the apparent drag race

Adding to the wood pile in Justin Bieber's DUI case, CBS4 obtained exclusive surveillance video footage, capturing the apparent drag race involving the 19-year-old singer and Khalil Sharieff.

Mere moments before the "Beauty and the Beat" singer was taken away by police, the home video captured a yellow Lamborghini and red ferrarri speeding down Pine Tree Drive, with a fleet of black Escalades running interference.
