This message is for homeland security re: Boston terrorist attack.
The purchase of pressure cookers is very miniscule. They should check every store within 25 miles of Boston for the purchase of these cookers. Interview every employee who have sold these and check credit cards against cash purchases. These are not sold often and when they are, they are normally purchased by housewives. Our family has always used them. Never have I ever purchased one of these.
I only post this because sometimes investigators have pipe vision and don't see the forest from the trees.
