not grassing probably cost me 6 months of my life in 1993.
i got involved in a large fight outside a nightclub that got very nasty-tools,people going through windows etc! out of the 8 of us on one side and the 10-12 on the other side,only 5 got dragged in.(me and a mate from my side).
the police were so desperate to get the names of the others but couldnt prove it,even though they were firing the right names at me. i kept quiet and said i didnt know....
it was brought up in crown court that i was not co-operative with the police= ended up with 12 months jail!
