shelters....
Open up the border to the dregs of society from 3rd world sh*thoies and act surprised when you begin housing criminals.
And as far as I know a criminal background check isn't going to do much good on folks here from Central and South America because I'm pretty sure countries in those areas don't enter their criminals into NLETS.
