CHICAGO (AP) -- It happened after Columbine, Virginia Tech, Aurora, Colo., and now Sandy Hook: People figure there surely were signs of impending violence. But experts say predicting who will be the next mass shooter is virtually impossible - partly because as commonplace as these calamities seem, they are relatively rare crimes.
Still, a combination of risk factors in troubled kids or adults including drug use and easy access to guns can increase the likelihood of violence, experts say.
But warning signs "only become crystal clear in the aftermath, said James Alan Fox, a Northeastern University criminology professor who has studied and written about mass killings.
"They're yellow flags. They only become red flags once the blood is spilled," he said.
2. Identifying may be difficult, but that doesn't meaN that programs can't help prevent violence.
The fellow who wrote a book about Columbine was on a couple of shows since Sandy Hook. One of the shoes was Up With Chris. He said that there are known diagnostic tools that can help diagnose depression in teenagers. He implied they are not that difficult to use. He also said he didn't think you could necessarily idenfify a mass murderer, but you could help a lot of kids with problems. One of those kids might have progressed to violence, but you prevented it from progressing. I'm paraphrasing, but I think this is a fairly accurate summary.n that?
So it's accurate to say that Identitying who is at risk for violence may be hard, we can identify those who are at risk and need help.
