I have no idea how many pressure cookers there are in the United States but I am sure it is well less than one per person. Actually, I am suspect the national average is less than one per kitchen, since many households won't have one and only a very busy cook would need more than one.
The point being that there are many fewer pressure cookers than guns in this country. As we learned in Boston, these pressure cookers can be the basis for a devastating bomb.
So, does Obama's common sense tell him we need a national pressure cooker registry with background checks required prior to purchase? I doubt there are Constitutional impediments. Engraving serial numbers on newly produced pressure cookers shouldn't be beyond the scope of our manufacturers. The cost to consumers will rise, but think of the children!
My suspicion is that Neither Obama's nor Bloomberg's common sense is taking them in this direction, but I am not sure why not.
WELL, YES: Ann Althouse describes Obama's tantrum after the collapse of gun legislation in the Senate:
Obama knew he was going to lose. The theater of sympathy and outrage had gone on far too long, the show was a flop, and the leading man was obliged to take his curtain call.
Ok, but it was a bit of a plot twist to see the leading man booing the audience. Not entirely unexpected, considering the leading man, but still.
