By the same token if we interned every muslim in the UK it would put a stop to Islamic terrorism overnight.I didn't advocate 'harassing the crap' out of any ethnic group, I advocate stopping and searching those the data indicate are most likely to be carrying knives, so if it it white males between the age of 16-25 in certain post code areas then 'harass the crap' out of them and if it p*sses them off then tough s**t because if it deters even some from carrying a knife then it's worth it.
And if we inter every white male between 16 and 25 it would nip right wing terrorism in the bud, too.
Likewise if you never fall in love you'll never have your hear broken.
Also, to avoid all possibility of accidents, sit quietly in doors.
This is all entirely logical. But it isn't right, is it?
