There are plenty of charities and other countries to support so called refugees. There always have been people fleeing violence and conflict but in the good old days they didn't have airlines, lorries and traffickers to bring them to our shores.
Your naive attitude is - give any piece of excrement who claim they are a refugee the benefit of the doubt, allow them to abuse our benefit system, let them put our citizens at risk by crime or disease, and when they are convicted of a crime spend further taxpayers money jailing them for X years before deporting them.
If you or your family become one of their crime victims don't say you weren't warned
