I guy I used to cycle with in Sheffield was riding home one night when two scroats tried to push him off the bike. Luckily he was a big lad and they failed, but he lost his rag big time, ragged it home, dumped his bike and grabbed a claw hammer and went looking for them! Luckily the two oiks, they were long gone by the time he made it back to the park.
As much as I can appreciate people wanting to defend their bikes, it is only a bike at the end of the day and not worth getting locked up for or stabbed. The law unfortunately in this country seems to do more for the criminal than the victim.
