NEW HAVEN, Conn. (AP) FBI Director James Comey says the agency has stepped up training to police departments around the country after the Newtown school shooting and is trying to increase its understanding of warning signs before such tragedies.

Comey, speaking at the FBI in New Haven on Friday, said the agency's behavioral analysis unit is working on indicators that might occur so authorities can respond. Comey, who praised law enforcement's response to the Newtown school shooting a year ago, says the training to state and local first responders is designed to help them respond effectively.

Comey expressed concerns about homicides in Connecticut's largest cities, saying a new task force would help address the violence. He also says cyber crime is a growing threat and budget cuts are leading to the elimination of 3,500 positions at the agency.
