Deporting all of the illegals would be a good start...
The DC area is overrun with illegals. On the Virginia side, especially in parts of Prince William County, there are large numbers of MS-13 and other Hispanic gang members. It is an interesting layout of the communities where the uber rich live in close in towns like Alexandria, Fairfax, etc., then there is a ring of lower priced communities filled with these kinds of people, then there is an outter ring of high priced, upper middle class.
Hey.. when will ENFORCING the law come back into vogue? /s
