It’s a harrowing video, taken from a security camera in Los Angeles last week. At the outset, traffic flows normally through the four-way intersection at South La Brea and Slauson avenues in L.A.’s Windsor Hills neighborhood. Then a Mercedes erupts from the bottom of the screen, moving so fast that it registers as little more than a blur. The car barrels through a red light and strikes several other vehicles, which immediately burst into flames. 

Six people were killed, including a pregnant woman and her 11-month old son.
