What people need to get their heads round is that migrants have always brought criminality to our shores. This is because migration is primarily undertaken by the poor and the dispossessed, some of whom will be highly aspirational, but others of which will operate on the fringes of society in order to survive. The opportunistic and the resourceful. The comfortably off, the unimaginative and the unambitious tend to stay at home, although migration as a result of conflict tends to alter that dynamic somewhat, for obvious reasons.
Criminal courts have had a hugely disproportionate number of defendants of Irish, West Indian and Pakistani backgrounds at various points since WW2, and today it's Eastern Europeans. If it wasn't people from these backgrounds, at the bottom of society, committing these crimes, then it would be indigenous Anglo-Saxons who occupied that place on the social ladder, burgling and committing street robberies. This phenomenon is as a result of the structure of our society - and nothing to do with race.
It is because our 'indigenous' population are either too comfortable, educated, inimical to getting their hands dirty - or crucially, old - that we are compelled to invite masses of people from poorer parts of the world to do our 'dirty work' for us - and there's a price to pay for that.
Peope want perfect solutions when none exist. Mass immigration needs to be managed; it cannot be quelled, or we will cease to function as a society.
