ATLANTA -- Seems like everywhere we go today, we're watched by cameras, especially in public places.

A retired GBI agent, who helped solve one of Atlanta's most infamous bombing cases, said that could be one of the keys to solving Monday's Boston Marathon bombings.

"When you saw all the people down on the ground who had been injured, (I) immediately flashed back to the Olympic Park," Charles Stone told 11 Alive News on Wednesday.

Stone said when he saw footage of two bombs going off in Boston two days ago, he was instantly transported back to the 1996 Atlanta Olympics when a similar backpack bomb went off during a concert at Centennial Olympic Park.

After seeing FBI photos of the remains of Boston's homemade pressure cooker bombs loaded with bb's and nails, he said they could have been even more deadly in the hands of a professional.

"I don't think it was a particularly skilled bomb builder," Stone told 11 Alive.

"He could have done a lot worse; using the same components, you could have built a better bomb," he added.

After three bombings in Atlanta, one in Birmingham and five years hiding out in the North Carolina mountains, anti-government loner Eric Rudolph was finally caught and convicted.

Stone co-authored a book called "Hunting Eric Rudolph" about his final case with the GBI.

While he sees many similarities with the two cases, he also sees one major difference.

"Since 9/11 especially, all major cities have cameras and the general civilian population, everybody's got a cell phone that'll take a picture," he said.

He believes those cameras which now surround us in most public places, including Boston, will help find the marathon bomber.

Those, combined with piecing together the bombs themselves, which Stone said are almost always unique to the maker.
