An Attempt to Kill an Ex-President, Caught in Real Time, Stuns the Country

It was the first attempted assassination of a current or former American president in the era of social media, and the conspiracy theories, finger-pointing and campaign gamesmanship moved at the speed of the internet, far faster than the actual facts of what transpired at former President Donald J. Trump’s campaign rally in Butler, Pa.

The assassination of John F. Kennedy in 1963 left the nation in bewildered grief. Conspiracy theories would proliferate, of course, and Abraham Zapruder’s film of Kennedy’s last moments would be studied for decades. But first, there was mourning. The assassinations of Robert F. Kennedy and the Rev. Dr. Martin Luther King Jr. in 1968 would rock the public consciousness again, leaving Americans wondering what would become of their country.

But in the era of memes, X posts, Truths, Threads and TikTok, introspection was never going to be the dominant mood. Rage, blame, even comedy were the watchwords of 2024. A picture of Mr. Trump, fist aloft, American flag fluttering overhead, became iconic in an instant.

Within minutes of the first televised images of Mr. Trump grabbing his wounded ear on Saturday, voices on the left were calling it staged, though they were hardly household names.

Not long after, far bigger names on the right, including Senator J.D. Vance of Ohio, a finalist to be Mr. Trump’s running mate, had settled on the argument that Democrats had set the stage for an attempted assassination by framing the 2024 election as a battle between the forces of democracy and the soldiers of fascism. Of course someone was going to take a shot, these conservatives said.

Before anyone knew a thing about the man who had pulled the trigger, Mr. Trump’s most senior surrogates, including Mr. Vance and Senator Tim Scott of South Carolina, were blaming President Biden and Democrats.
