Few details missing then?
to be honest that looks more like a bunch of glue sniffers trying to steal a bike, not a gang, but then again, a good gang would prefer that, but i doubt they would risk doing it in front of clear cctv
another good reason to wear safety gear - punches hurt less, and yours hurt more, careful out there people - very few people would step in and help, i'd like to think i would be one of those, but i will not be bigheaded enough to say that with any confidence until it happens
and after saying that, i can say this without feeling like i am going to be acting superior, what the hell were the people in the other vehicles doing? watching? c*nts :)
the forecourt staff watch you like hawks in my experience, especially if you don't take your helmet off, i also don't beleive their answer, they just didn't care at the time, and they feel guilty when questioned about it.
can you buy brass knuckle armour instead of kevlar? :)
