it was a day of high emotion at the hearing led by peter king investigating the extent of radicalization of american muslims. i was struck by a comment made by a quiet man from memphis, tennessee. melvin bledsoe lost his son carlos to radical islam. once a happy-go-lucky boy who always apparently had a smile on his face, melvin says carlos was brainwashed by an imam to hate americans. he now stands accused of killing an american soldier in arkansas. bledsoe expressed the hope that his pain could open eyes to the threat. >> i don't understand why we have so much fear of talking about what is real. it is a real threat to america, as i said earlier today. it came into my house but is at your doorstep. we need to talk about it as american people.
