In regard to the Second Amendment, it is instructive to note that it does not address 'need.' No one was asking, "Why do you NEED a .50 caliber, rifled barrel muzzle loader?" Today, the sycophants on the wrong side of the Constitution ask "Why do you need a 30 round magazine? " You may as well ask "Why do you need that large truck"...or "why do you need another beer?"
We tread on thin ice when people in high office, of low virtue, think that they are the arbiters of what The People NEED! What the people NEED is for men and women in power to concern themselves with assuring that Liberty is expanded and not constricted! The Constitution begins "We, The People"..and not "We The Elite Rulers and Arbiters of ALL NEEDS for the peons."
