Guess what... you join in with a mob like that, you affiliate yourself with them, be prepared to deal with the consequences. That's life: choose your friends carefully because you might pay for their stupid actions. Don't tell me you're naive enough to not have realized that by now.
And umm, I'm sorry, if you're afraid for you and your family's life and a mob is attacking your car and slashing the tires, you are ALLOWED BY LAW TO ESCAPE, even if it means using self-defense (in this case, the person's vehicle.)
I don't know what La-La Land you live in, but this is the real world. If you need to defend yourself, you do so. If it's you, your wife, and a fucking baby against 50+ dudes on motorcycles... I'm sorry but they took their own lives in their hands when they decided to assault a 5000 lb vehicle while they're on motorcycles.
Deal with it.
Edit: Basically, everyone in these two threads saying the SUV driver is at fault is basically saying it's OK to assault someone and their family, to gang up on people and do commit illegal acts of violence and intimidation, and if the person defends themselves, they will be the ones in trouble because you should be able to assault and attack people in groups. Am I wrong?
Must be nice to live in La-La Land...
