At least for some law enforcement agencies. Take a look at the picture of the heavily riddled pickup in the video at this CBS Los Angeles account. Early accounts indicate that police have opened fire on two different trucks now without bothering to give orders to stop, leave the vehicle. It is pretty clear that there some law enforcement agencies that can't be trusted with repeating weapons.
Oh yeah: they are chasing a former cop, alleged murderer, who has been spouting gun control and pro-Obama rhetoric while running around shooting people.
