1967 - Jayne Mansfield is killed when her car runs under the rear end of a tractor trailer. Since then, all trailers have a DOT bar at the rear to keep cars from going under them.
1982 - Seven people die when Tylenol packaging was tampered with. Since then, it takes a PhD, channel locks, and a sharp object to get into a bottle of pills.
2001 - One person attempts to blow up a plane with a shoe bomb. Since then, all air travelers have to take off their shoes for scanning before being allowed to board.
Since 1968 - 1,516, 863 people die from guns on American soil. Since then, the problem apparently can't be solved except with thoughts and prayers.
