Reports out of Boston claim that the bombs were transported in pressure cookers.

Long ago, my wife's step-father and his brother owned the appliance repair store in New York. Many of the major manufacturers designated their store as the place to go if your iron or toaster broke.

One day, into the store walked Golda Meir. She was in New York to address the UN or something like that. She brought her broken pressure cooker all the way from Israel to get it fixed.

Okay, just kidding. Here are some real marks: 

A 2010 release from the Department of Homeland Security said pressure cookers "frequently have been used in Afghanistan, India, Nepal, and Pakistan. Pressure cookers are common in these countries, and their presence probably would not seem out of place or suspicious to passersby or authorities."

At least two previous terror plots in America included pressure cookers. One of the explosives Faisal Shahzad left in Times Square was a loaded pressure cooker, the DHS release said. And in 2011, Army Pvt. Jason Naser Abdotold investigators he planned to pack gun powder and shrapnel into pressure cookers as part of an attack on a restaurant popular with personnel from Fort Hood. When he was arrested, Abdo had a copy of Inspire magazine and explosive supplies and two pressure cookers.
