NEW YORK ( TheStreet) -- As a parent and educator, I want children safer from gun violence. However, we should seek measures that work -- not those that needlessly abridge personal liberties without producing significant results. Whatever we accomplish should not be at the expense of raising children to be secure and capable adults.Skepticism about tighter gun controls is understandable. Connecticut already has some of the toughest laws in the country -- background checks are required and assault weapons are banned. Yet, the guns at the Newtown massacre were legally purchased by the alleged murder's mother. In 2011, dozens of people were killed at a summer camp in Norway, which has some of the toughest gun laws in the world. Banning assault weapons -- those not requiring reload to fire repeated shots -- nationally might help but won't end gun violence. The 2002 Virginia beltway snipers killed 10 and critically injured others over several weeks, but that could have been accomplished with single shot hunting rifles. Engaging the mental health community, as often suggested, to better keep weapons out of the hands of the mentally disturbed could set troubling precedents. Compelling doctors and counselors to blacklist citizens, who have not committed a documented act of violence, simply because they might be so inclined could easily lead to abuse -- but if not zealously undertaken, such efforts would prove ineffective. Even then, the deranged could steal weapons -- the gunman who killed two people and himself at an Oregon shopping mall earlier in December used a stolen rifle. Several jurisdictions around the country have installed metal detectors at schools and keep doors locked to outsiders; however, unless we want to turn our schools and universities into prisons, with high walls around their grounds and seriously limit the movement of students outside their buildings, they can't be made wholly safe. Severe measures could easily make young people overly fearful and suspicious, and ultimately create apprehensive and distrustful adults -- too insecure and rigid to advance our civilization as it must in the face of new challenges.
