ALBANY, N.Y. -- "They are not taking direction from a centralized headquarters," says Dr. Jean Stern, a Globalization Studies professor at Siena college, says while little is known about the motive of Dzhokhar and Tamerlan Tsarnaev, we do know they are from Chechnya, an area with a deep history of volatility.
"They grew up here and we don't believe they went back to Chechnya to be trained like the other groups have done, so their connection to the Chechnyan rebellion is very tenuous," said Stern.
If that played any part in their motives to allegedly bomb the marathon, that remains up in the air.
Dealing with these smaller terror cells, many experts say, changes the playing field for investigators.
"Go with your gut instinct and notify law enforcement because law enforcement is going to have a tough time keeping track of these individuals," said terrorism and law enforcement expert Bill Peeler.
"It will be difficult to develop a strategy to keep track of them," said Stern. "There is so much more to pay attention to and they all have different reasons for what they're trying to do and that is why they're engaging in terrorist attacks."
"We don't want to be a policed state but we need to find that middle ground between being a policed state and having a free country and having the rights we have been given at the same time," said Peeler.
