I didn't say it would solve everything. There is no one solution that will fix everything. But it would solve a lot: This shooter in Colorado; Omar Mateen, who shot up a gay nightclub; the Tsarnaev brothers, who bombed the Boston Marathon; Syed Farook & Tasheed Malik, who shot up a Christmas party, Nidal Hasan, who shot up Fort Hood; Nasim Aghdam, who shot up the YouTube offices.
Why were any of these people even here? They weren't *born* here. They had no right to be here. Our government *chose* to let them in and endanger *us*. Why?
