I don't agree with these comments made by Jack Straw myself. But we as migrants should try not to give excuses to people like him to malign our communities. I mean why did he single out Pakistanis? He could have said "All asians". Surely there are some Pakistanis in Britain who are doing something wrong don't you think?
And as for the link about the claims i made, it was published by Australian Bureau of Statistics. They have an online version but it doesn't include data for all countries. And you need to pay some fee if you wan't the complete data. I have sent them an email saying how i need it for Uni research work, will see if i can get it for you.
