Someone's always watching. From a distance cameras aren't easy to spot, but they are there, helping capture whatever is in sight.
"It definitely gives us an advantage when we start our investigations," said Corporal Christopher Levy with Mobile Police.
Levy relies on surveillance video to piece together crimes. Every now and then law enforcement gets lucky and they're able to use screenshots to locate a suspect.
"We use cameras for a number of investigative purposes. We have our own cameras that are stationary at different places around town but also when we have an incident that occurs we often get cooperation from those businesses to use the cameras," said Corporal Levy.
The FBI released two surveillance photos late Thursday afternoon of the suspected men behind the Boston bombings. Officials are hoping these photos help locate the criminals.
So, whether you're at a bank, in a gas station, or in a store, know that somewhere there's a camera keeping an eye on you.
Law enforcement officials in Boston know their surveillance footage may help find the two suspects. The video screenshots are now being seen around the world.
