For christ sake people, lighten up, I was being a smart ass. Give me a ****ing break! Youdon't have to be *******s about something I say.
More then likely I would place the driver in my cruiser until back up arrived to protect him or her from the mob. First I would try words to keep the mob back, then if needed I'd draw some sort of weapon, starting with a less then lethal as a threat of force to keep the mob at bay. As a last resort I'd draw my firearm as a method to keep the mob at bay. I would first try to use the weapon as a show of force, then if I had to I'd fire.
Typically when it comes to mob mentality when you just show a weapon as a show of force when one person in the mob backs down they all follow suit.
If the driver is found to be at fault I would probably like to turn his or her ass over to the mob but instead I'd arrest him or her & take them to jail if it was an arrestable offense, otherwise he or she would probably get a ticket & be sent on their way.
