It's simple really. The lefties inviting the immigration boom never thought through the practicalities. Discussion on how to manage crime and integration problems was stifled, it was seen as racist to suggest we might see a wave of sexual crimes, petty crimes, terrorism, welfare abusers and unemployment.
The left promoted the high education levels in Syria, the comptibility of Syrian culture with the west, the humanitarian mission to help people. Judging by the comments I see within my Facebook friends (mostly lefties), they are genuinely shocked and disappointed that the a large number of immigrants are misbehaving, and not employing themselves by setting up cool new districts with funky ethnic restaurants and music.
We are just in the beginning of the discussion that should be had before announcing open house. From there we can begin to set up procedures, policies, changes in legislation, resource the forces requiring more manpower etc.
