Once in a while a madman like the Virgina Tech killer beats our system, -- making it obvious, -- that this is why everyone in system should be armed [as per the 2nd].
Your opinion of "if dangerous on the streets you belong in jail" sure would be nice, ---
--- yes, there are a few people who are just not able to take care of themselves, not able to function, no one to care for them but have not been proven to commit a crime; what do YOU propose we do?
As I said above, constitutionally speaking we can do nothing. Unless adjudicated 'dangerous', they have a right to arms, to self defense.
When, -and if-, these people become dangerous, - using arms criminally, -- they will be taken out by the rest of us.
It isn’t once in a while that a madman beats our system. It is almost continuously. Remember the guy that shot up the mall in Kansas City? He attempted suicide the previous October. He was hospitalized for 6 1/2 hours, then released.
Patrick Purdy? Long history of mental illness—and when he finally did something “serious,” it was to murder five children, wound 29 others, and provide the impetus for passage of the various assault weapon bans of the 1989-92 period.
Does the name Larry Gene Ashbrook ring any bells? Killed seven people in a church in Texas in 1999. Long history of mental illness that would have locked him up in 1960.
Does Russell Eugene Weston, Jr. ring any bells? Long history of mental illness and short commitments for violence, before he shot to death two police officers at the Capitol in 1999.
Remember the guy who shot up the Jewish community center in Granada Hills, California a few years ago, scoring many points for the gun control crowd? He actually tried to get himself into a mental hospital, but a judge refused to listen to his talk about mass murder, and released him, rather than hospitalized him.
