Jagermeister,
Everyone probably wishes it could be that easy, but it's not. In my police state they took away the right (years ago) to own a fully automatic weapon even with a Class III license. We have a Firearm Owner's Identification requirement to purchase, transport or possess a gun of any type. And the Brady Bunch with their waiting period is also in effect. Now our big city mayor has banned handguns, clips that hold more 10 rounds for pistols, and even shotguns that hold more than 5 rounds.
Better to support the NRA and take the stance that once one gun type is banned, the next step is to ban them all.
The Police can't help us. They only show up after the tragedy has already happened and you're dead. Far better to simply arm everyone so the next "whacko" can be stopped immediately with extreme prejudice.
