The FBI is relying heavily on surveillance video near the finish line at the Boston Marathon to piece the attacks together. Those cameras are becoming another arm of law enforcement. Providence also has plenty of them.
There are more than 200 surveillance cameras in downtown Providence alone, watching us 24 hours a day, and police said those cameras help them solve most crimes.
"They are a great tool, a great piece of evidence for law enforcement," said Providence Police Chief Hugh Clements, "A picture tells a thousand words."
Chief Clements said the cameras play a huge role in solving most crimes, "We've used them in criminal investigations involving assaults, felony assaults, robberies, disorderly conducts."
They've been in the city for more than a decade, but are getting more attention now, as video of possible suspects in the Boston Marathon bombings is providing police with solid leads.
"We know we have a lot of large scale events with high volumes of people between road races, Waterfire, other major events in the city, so sure it's going to be a concern for us during the Summer," said Chief Clements.
Waterfire alone draws more than a million people into Providence every year.
Security experts said there's one problem with the cameras, especially the cameras on businesses owners pay for out of their own pockets.
"They're putting in video cameras that once they're reviewed on the DVR the quality is so bad that you really can't see faces, you really can't close in on something," said Vic Pichette of Genesis Investigations.
There's been no talk since the bombings to add more cameras in Providence, but police are considering beefing up security at outdoor events. There are no specific changes at this point.
