“Police in Dearborn [Michigan] are trying to understand why a pressure cooker was left in the restroom of the Adoba Hotel, forcing the evacuation of guests until the early morning hours. The evacuation also canceled Sunday night’s banquet of the University of Muslim Association of America,” reports CBS Detroit.

“The pressure cooker discovered at the hotel was detonated by police as a precaution, but contained no explosives.”

Sure, after the Boston Marathon bombing, pressure cookers have entered the terrorism lexicon. But, what do you think? Was this a practical joke? A political commentary? An episode of forgetfulness on the part of the cooker’s owner?
