Boston Police Chief Urges Surveillance Increase After Attack

Boston Police Commissioner Edward Davis urged Congress to fund more surveillance of public places after the bomb attack on the Boston Marathon that killed three people.

Davis, who helped lead the law enforcement response to the April 15 attack, said investigators had to rely “almost exclusively on the support of our business partners” for the video surveillance that helped identify the suspected bombers, Tamerlan and Dzhokhar Tsarnaev. Davis said law enforcement needs an enhanced ability to monitor public places on its own.
