FBI and Massachusetts Police are investigating reservoir Tresspassing?

Well as if the Boston Marathon Bombing and the Mothers Day walk shooting didn't scare us enough. Now the FBI are investigating a group of Seven people and two cars seen trespassing at the Quabbin Reservoir which supplies drinking water to Boston.

The 7 people were identified and questioned as to why they where trespassing. They claim to be recent Chemical Engineer graduates curious about the reservoir. This seems very suspicious but the FBI has assured they have no terror links to this incident that they know of. 

We are living in an unsafe world but i think there should have been more investigation into this matter before they leaked this to the public. keep your eyes and ears open everyone.
