By definition criminals don't obey laws; new ones or old ones. Why would we want to prohibit or inhibit the only means we may have to protect ourselves or others from someone who is armed with the intent to harm? Making more laws only restrains law abiding citizens not criminals. Shouldn't we be trying to make deterrents to criminal behavior rather than an incentive? What better incentive for gun toting criminals than to create an environment where he has the only guns.
