As I said, an open discussion should allow such things to be discussed.
Be careful though of the Daily Mail trap: 'conflating immigrants that are criminals', and 'all immigrants are criminals'.
Thats the problem with newspapers. Reports of 'Albanian pickpockets on London streets' - seems to feel like its all Albanians, then its not far for that to become 'sll immigrants are thieves.
Of course some criminality is imported, but lets be clear: the majority of immigrants are honest and they dont want criminal coming here any more than you do.
