Alexander Cockburn makes a well reasoned argument in "Counter Punch":
Bring       Back the Posse
        By ALEXANDER COCKBURN
        Since there undoubtedly will be a next       time, probably in the not so distant future, what useful counsel       on preventive measures can we offer students and faculty and       campus police forces across America?
        There have been the usual howls       from the anti-gun lobby, but it's all hot air. America is not       about to dump the Second Amendment to the US Constitution giving       people the right--albeit an increasingly circumscribed one --       to bear arms.
        A better idea would be for       appropriately screened teachers and maybe student monitors to       carry weapons. A quarter of a century ago students doing military       ROTC training regularly carried rifles around campus. US Supreme       Court Justice Antonin Scalia recently recalled regularly traveling       on the New York subway system as a student with his rife. Perhaps       there should be guns in wall cases, behind glass, at strategic       points around campuses, like those fire axes, usually with menacing       signs about improper use.
        Five years ago Peter Odighizuwa       a 43 years old Nigerian student killed three faculty members       at Appalachian Law School Dean with a semi-automatic handgun,       but before he could wreak further carnage two students fetched       weapons from their cars, challenged the murderer with guns levelled       ,and disarmed him.
        When the mass murder session       began in the engineering building the police cowered behind their       cruisers till Cho Seung-Hui finished off the last batch of his       32 victims, then killed himself. Then the police bravely rushed       in, started sticking their guns in the faces of the traumatized       students, screaming at them to freeze or be shot. Similar timidity       was on display in Columbine, where Harris and Klebold killed       students in the library over a period of 15 minutes and then       committed suicide. The police finally mustered up the nerve to       enter the library over two hours later.

The answer is to disband SWAT       teams and kindred military units, and return to the idea of voluntary       posses or militias: a speedy assembly of citizen volunteers with       their own weapons. Such a body at Columbine or Virginia Tech       might have saved many lifes. In other words: make the Second       Amendment live up to its promise.
        I....... If you confer the task of social invigilation       and protection to professional janissaries--cops -- and deny       the right of self and social protection to ordinary citizens,       you end up with crews of over-armed thugs running amok under       official license, terrorizing the disarmed citizens. In the end       you have the whole place run by the Army or the federalized National       Guard, as is increasingly evident now with the overturning of       the Posse Comitatus laws forbidding any role for the military       in domestic law enforcement.
        What should be banned from       campuses are not weapons but prescriptions for antidepressants.       Eric Harris, co-slayer (with Dylan Klebold) of twelve students       and a teacher in the Columbine school shootings in 1999, was       on Luvox, a Selective Serotonin Reuptake Inhibitor (SSRI) of       the same class as Prozac, Zoloft, and Paxil. Initially Harris       had been prescribed Zoloft, but told his doctor he was having       suicidal and homicidal fantasies. So the doc shifted him to Luvox.
        16-year Jeff Weise, who killed       10 schoolmates at Red Lake High School on an Indian Reservation       in 2005 was on Prozac. The manufacturer said 4 per cent of children       in one of its tests of Luvox developed short-term mania. Other       studies of the SSRI anti-depressants have claimed they have a       15 per cent chance of prompting suicidal or homicidal reactions.
        Cho Seung-Hui was on a prescription       drug for his psychological problems. What exactly it was not       yet been disclosed, though the likelihood of it being an anti-depressant       is high, since doctors on campuses dispense prescriptions for       them like confetti.
I agree on both points - while I advocate the right to bear arms, it comes with responsibility and obligation to protect society. I believe we should take Cockburn's citizen militia argument one step further and develop an army like Switzerlands- strong, competent but for defensive purposes only ....of course the empire builders like the Neocons don't like that idea- all the more reason it ought to be initiated.
Of course this and other freedoms in the constitution require a cohesive society - and deep understanding of the culture that brought them about - another thing glboalists don't want....its no surprise that the Neocons like John Podhoretz came down on the side of gun control and chastized people like John Derbyshire and Michelle Malkin for calling the military service age males cowards for running away (while a 76 year old professor - survivor of Facism and Communism gave his life protecting his students).
