I don't see anything to do with arabs or muslims there.
anyhow.
stabbings are mostly gangs.
black on black. There are many bangladeshis(bangladesh is a muslim country) that are screw ups too. So they form asian gangs.
One of the hilarious comments there was "I've got to go get me a knife before I get attacked by my evil twin"
It is a stupid advert..
But if they had said "Don't carry a knife, or you may get stabbed by somebody", that wouldn't have worked!
or "Don't carry a knife, or you may stab somebody" That won't work either.
Nobody is going to fall for this advert anyway.
Point is.. I think People can be arrested if caught carrying a knife..
this is just some silly attempt to get people to stop carrying them, to save the police some work.
I doubt the police will be seraching people properly though.
