Beto argues for gun buyback while speaking at Kent State, saying students were killed there. He didn't mention the government shot them.

Democratic presidential candidate Beto O'Rourke continued his campaign for a U.S. gun buyback program during a stop at Kent State University this week, and noticed that peaceful observers who were lawfully carrying firearms attended his rally.

After the event, O'Rourke took the opportunity on social media to accuse the observers of bringing "assault weapons" to a campus "where four students were shot dead in 1970" — omitting the fact that the students killed were shot by the Ohio National Guard, not civilians.

What are the details?
On Thursday, O'Rourke posted a video of part of his gun control speech on Twitter, with the message, "Yesterday, people brought assault weapons to our rally at Kent State — where 4 students were shot dead in 1970. I told them nobody should show up with an AK-47 or an AR-15 to seek to intimidate us in our own democracy. We need to buy back every single one of them."
