The definition of insanity

One of the coloquial definitions of insanity is "Doing the same thing and expecting a different result."

Like with the DC gun ban:

Feelings Mixed Over Pending Ruling on DC Handgun Ban

Of the folks interviewed, one person after another supported the 2nd Amendment -- except for DC, where the 32-year experiment in disarming honest, law-abiding citizens has been an unmitigated disaster. They wanted to keep the citizens of DC disarmed, to maintain the city as what it is right now: a huge population of sitting ducks.

If disarming honest, law-abiding citizens turns your city into Murder City, USA, maybe it's time to call the experiment a total failure and do what has actually worked elsewhere to reduce violent crime: Let decent, law-abiding citizens had the right to defend themselves, their families, and their neighbors.
