violence, knives being drawn, drink driving, someones going to be in the shit

it's a bit unclear though so is this anything like it?

subjects a, b, c, d, and e go out for a drink
who got agressive with who? one of your housemates?
so the weakling gets a blade and get's knocked out?
and then gets knocked out again
then jumps on someones car
then gets done for drink driving?

depending on who the judge believes, and this will come down to a judge if things go on, your mate who landed the blows could be in deeper deep shit than mr drunk driver

he can turn around and say he was defending himself and, for fear of his own life, he drove away as he couldn't defend himself because he was pissed

it's a bit of a sticky situation as well because you can't really go round asking for "advice" on a forum as it might be benificial/prejidicual to the case in question
