Back in 1835, there was an attempt to kill Andrew Jackson. If I remember my history, the shooter was adjudged mentally incompetent and permanently locked up in an asylum.

Today he would be medicated and put back on the streets. The government would then ban the guns he used.
Richard Lawrence was the shooter.

Lawrence told doctors later his reasons for the shooting. He blamed Jackson for the loss of his job. He claimed that with the President dead, “money would be more plenty” (a reference to Jackson’s struggle with the Bank of the United States) and that he “could not rise until the President fell.” Finally, he told his interrogators that he was a deposed English King—specifically, Richard III, dead since 1485—and that Jackson was his clerk. He was deemed insane and institutionalized.
They were so judgmental in those days. He just had a different POV. /s
