The buying frenzie isn't started by the the evil act, the frenzie starts in anticipation of a ban or partial ban on weapons, ammo or both. Bans are signed into law or tolerated by the POTUS. In 2012, the buying frenzie started because 0bama and his willingness to ban guns.I think the Senate and House of Representatives are much more threatening to gun bans than the President, regardless of who is currently President. And the mass murderers have given much more to the manufacturers/NRA than the President could ever dream of.
