US will learn the hard way that you can't fight radicalization with guns. There's intelligence that some members of the national guard could perpetrate violence during the inauguration i.e. an attack from within.
This has forced the FBI to vet all those national guard officers who will be deployed during the inauguration.
Radicalization is a mental health condition. The only place you can win against radicalization is in the mind. No intelligence or military might can win a war going on in an individual's head.
