I gave up my day job so that I could educate my son at home. Meanwhile, my tax dollars are supporting the education of the kids next door. I believe that there is a place for public access to education. As a home educator and a Libertarian, I do not believe that tax-funded vouchers are the answer. But I do believe that government, state and federal, should get out of the business of education.
Criminals are, by definition, lawbreakers.
Laws that prohibit honest citizens from carrying firearms, whether it be in parks, schools, places of employment, whatever, will be roundly ignored by criminals. Every citizen has the right to defend himself with whatever means he sees fit. No government, at any level, has the right to deprive its citizens of the right to defend their lives.
