Most of the people in this part of the country know there is a problem but realize most of the illegals, as well as the drugs, are bound for "somewhere" else. It's not like this just began on 9-11.

Not all is headed somewhere else and that somewhere else is still being sold to American children. No, it's not like this just began on 9/11, but it has definitely escalated to the extreme.
