FRIDAY, July 29 (HealthDay News) -- Any time there's a violent tragedy -- the killing of at least 86 people at a youth camp in Norway, the shootings of a congresswoman and others in Tucson, the Virginia Tech massacre -- one question seems to ring clearer than others: Why didn't someone notice beforehand that the suspect might be disturbed and capable of committing deadly violence?

The irony is that people suffering from delusions and clearly mentally ill, he said, are less likely to commit violence than people teetering on the brink of obsession who are not technically suffering from a mental disorder.
"People who have overvalued ideas often act on them," Wise said. "People with delusions do no
