The man who attempted to kill President Ronald Reagan has weighed on the state of political affairs after Saturday’s attempted assassination of former President Donald Trump.

“Violence is not the way to go. Give peace a chance,” John Hinckley posted on X.

Hinckley was 25 when he shot and wounded the 40th U.S. president outside a Washington hotel. The shooting paralyzed Reagan press secretary James Brady, who died in 2014. It also injured Secret Service agent Timothy McCarthy and Washington police officer Thomas Delahanty.

Jurors decided Hinckley was suffering from acute psychosis and found him not guilty by reason of insanity, saying he needed treatment and not life in prison.

Hinckley was released from all his remaining restrictions in 2022. On social media, he now sometimes sells art he makes of animals.

On the surface the parallels between 1981 and what happened Saturday in Butler, Pennsylvania, when a gunman fired shots at Trump, are striking.

A gunman got off several shots as Trump was addressing a rally crowd, and Trump was struck in the right ear. Trump ducked behind a lectern as agents piled on top of him as human shields.

In what is sure to be an iconic moment, a bloodied Trump raised a defiant fist to the crowd as agents whisked the presumptive Republican presidential candidate off the stage.

Reagan, lying on a gurney in the trauma bay, a chest tube draining blood from his side, sought to calm down his wife, Nancy, with a quip.

“Honey, I forgot to duck,” he told her, borrowing a line that boxer Jack Dempsey delivered to his own wife after losing the 1926 heavyweight championship.

And just before he was put under for surgery, he cracked to his surgeons: “I hope you are all Republicans.”

Dr. Joseph Giordano, a liberal Democrat, replied: “Today, Mr. President, we are all Republicans.”

The White House wasted little time in ensuring those lines were delivered to the press.
