From the Washington Post:
We assess that most foreign-born, US-based violent extremists likely radicalized several years after their entry to the United States, limiting the ability of screening and vetting officials to prevent their entry because of national security concerns.
So a 90 day ban does nothing to prevent Muslim immigrants from radicalizing years later, right?
This is looking good, this ban thing, and the Mexican wall, that shit is looking fabulous so Trump is killing it people. Killing it!
