From The American Spectator:

Murderers with poisonous ideologies have taken the lives of innocents once again. And the response is the same as it always is: Politicians turn to the proven solution of creating yet more felonies to criminalize law-abiding gun owners.
Won’t it be fun to imprison an elderly widow who transfers her husband’s old shotgun to a neighbor without a background check? Or give a felony record to a young worker who has a rifle the bureaucracy classifies an “assault weapon” because it has one of those deadly adjustable stocks?
