'I'm Not Going to Sleep': Victim's Father Calls for School Safety Laws at Trump Session

Florida Student: State Lawmakers Who Refuse to Act on Guns 'Won't Get Re-Elected'

During a listening session with school shooting victims' families and friends, President Trump agreed with a participant's contention that faculty should be properly trained and armed if they choose.

Trump said background-check policy must also be very strong as well.

"After we do that, when we see there's trouble [with a potential suspect] we have to nab them," Trump said.

He called for a new focus on preventing disturbed individuals from having the chance to commit a heinous crime like a mass shooting.

Trump said gun violence prevention is only effective when faculty are properly trained in handling weapons.

"A gun-free zone to a maniac -- because they're all cowards -- a gun-free zone is 'let's go in and let's attack because bullets aren't coming back at us'," he said.

"If these cowards knew that the school was well guarded ... I think they wouldn't go into the school to start off with," Trump said.

He lamented the recent drawdown of psychiatric hospitals over the past few decades, calling them a "middle ground" for someone who is exhibiting worrisome behavior but has not perpetrated a disturbing act.

"There's no place to bring them, and we have that a lot," he said.
