Exactly. I imagine there's a defence for pretty much any charge if you look hard enough for one. Aside from the damage to the car they're also distracting the driver by putting his window through etc. How they or anybody else can genuinely believe that would help the situation is beyond me. Would they have acted like that individually? Highly doubtful.
The drivers acted like a **** we can all agree on that. He will get what is coming to him. I know I wouldn't have ended up mowing people down, but I genuinely don't know how I'd have reacted if my car was getting attacked by all sides. Stay stationary? No... Get out the car? Certainly not. That's having time to think about it, not being on any drugs and having to act in the moment.
