Oh, lookie!  Another crazy guy with a gun, a threat to himself and to others - as was his ammo.  But our pro-gun readers would fight tooth and nail any attempt to stop people like this from endangering people like the rest of us - or himself.

Package Dropped by Suicidal Man Highly Explosive

Police in southern Wisconsin say a package dropped by a man who shot and killed himself was highly explosive.
Authorities say the 35-year-old man shot himself in the chest with a muzzle-loaded gun on the sidewalk of a residential neighborhood in Waukesha Tuesday night. A 3- by 4-inch package fell near the man.
Police say the man killed himself shortly after officers were called to the neighborhood by a friend of the man. She told police he was suicidal, possibly had a gun and possessed bomb-making material.
Suspecting the package could be explosive, officers called the Milwaukee County Bomb Squad which detonated the device. Police Capt. Ron Oremus says it contained black powder and ammunition. He says a suicide note and bomb-making equipment were found in the man's residence.
