As you'll know, they're in league with the cops anyway.
They've been doing that stuff in Ermita for many years.
I remember getting my pocket picked there in 1990 ...probably by their parents.
Forgot to mention, if someone is unusually pushing/pressing on you...or you can feel a woman's bosom by ur side, chances are they have their hands in ur pocket.
By the way, which technique did they apply on u Graham?
