At the age of 18, an American citizen can join the military get issued an M-16 and have their legs blown off by an IED in Iraq - “for freedom.” However, if that 18-year-old wants to buy a handgun in the same country that sends them off to have their legs blown off, they are banned from doing so - because “freedom.” All that could soon be changing now, however, as the U.S. Court of Appeals for the 4th Circuit has ruled that laws preventing 18-20-year-olds from buying guns are unconstitutional. In a split decision, the three-judge panel ruled on Tuesday that the minimum age requirement of 21 to buy a gun in the land of the free restricts the rights of law-abiding citizens by drawing an arbitrary and unjustified line.
