Your ABC new poll 'Is Shooting Grounds for Gun Control' is very poorly stated. The options offered, 'No, because violent shootings are isolated incidents', or 'Yes, because this shows the violence that can occur when someone has access to handguns' show your editorial board's bias against firearms. I don't know anyone who would use this reasoning to justify a 'no' answer. A simple 'yes, no, or undecided' would have been a much more fair way of wording this poll.
My answer would be no, with a much different justification: If Virginia Tech were not a 'gun free zone', as nearly all schools in this nation are, it's possible that one of the students or faculty present would have been able to put an end to the shooting before 30+ people had been killed.
Virginia has a concealed carry permit system, and by state law, it's permissable to carry a concealed firearm on a college campus. Virginia Tech has a policy against doing so. A bill proposed last year that would have made carrying on campus legal, despite the college's policy, never made it out of commitee.
It's time to reconsider the failed 'gun free school zone' policy. A lunatic who is seriously considering entering a school with the intent to murder dozens of innocent people isn't going to obey a 'no guns' sign, any more than they are planning to obey the law that makes it illegal to kill innocent people! These signs insure that there will be no legally armed citizens available to put a premature end to such a rampage. Notice that there were no insane gunmen shooting up last weekend's NRA convention in St. Louis.
Judging by the response to your very poorly worded poll, with 10,000 more 'no' votes than 'yes' votes at the time of this writing, I'm not the only one who sees the logic in allowing legally armed citizens into our schools!
