LOS ANGELES (CBSLA) — The Los Angeles Police Department Deputy Chief crossed the street out of uniform Thursday to see who would, and more importantly, wouldn’t stop at a pedestrian crosswalk.

The department shared a video of Deputy Chief Blake Chow crossing the street on Twitter, saying “Today, LAPD Deputy Chief Blake Chow literally put his safety on the line to catch drivers failing to yield to pedestrians in the crosswalk. You be the judge…violation of 21950 of the California Vehicle Code?”

At least eight vehicles could be seen driving through the crosswalk before a driver finally stops as Chow inches into the street. Multiple cars in other lanes failed to stop as he slowly made his way across.
