John Hinckley Jr.

The would-be assassin and aspiring country singer made the comment after his latest concert was postponed indefinitely.
The man who shot Ronald Reagan in 1981 said his new National Redemption Party opposes “the Mob that controls the music industry.”
Mark David Chapman said the decision to kill the former Beatle was “my big answer to everything. I wasn’t going to be a nobody, anymore.”
“I feel terrible for what I did,” Hinckley told CBS News. “If I could take it all back, I would. I swear — I would take it all back.”
Hinckley shot Reagan after becoming obsessed with Jodie Foster in the film "Taxi Driver."
