Saturday’s assassination attempt on former President Donald Trump was a crime against the entire country and against democracy itself. Every American should be grateful that it failed, and that Trump has survived it.Let’s say it plainly. It is an abomination that he was wounded as he campaigned for a return to the White House. Every one of us has an obligation to examine what we can do to stop any kind of recurrence.We are grateful that, as The Washington Post notes, “Leaders of both political parties, including some with whom Mr. Trump has clashed, swiftly and unequivocally condemned the attack.” They are setting the right example in an otherwise toxic political environment.We have lived this national nightmare too many times. In the last 60 years, we’ve had the assassination of President John F. Kennedy, of Medgar Evers and the Rev. Dr. Martin Luther King, of Robert Kennedy, and the assassination attempt on President Ronald Reagan.In May of last year, another assassination attempt was foiled when a 19-year-old man drove a rented van into a White House barrier. He was a Nazi sympathizer who was prepared to “kill the president” and “seize power.” Saturday’s shooter, 20-yearold Thomas Matthew Crooks, apparently used an AR-15-style automatic rifle.As we have before, all of us will live through the trauma of seeing the attempt on Trump’s life replayed over and over on the news.Political violence is never acceptable, and attempting to assassinate a candidate for public office, much less the presidency, is particularly abhorrent. Once killings of leaders, political candidates and presidents become embedded in a nation’s history, neither figures on the left nor the right are immune.We are grateful for the courage of Secret Service agents and first responders who acted quickly to protect Trump. But we need to stop putting them in harm’s way in ways that have become too common.However, rooting out political violence will not be easy.In our society, as political polarization has increased, so has approval of violent means for partisan ends. An April 2024 PBS NewsHour/NPR/Marist poll showed that one in five Americans believe that political violence may be justified.At the time, experts said these figures put the nation in “an incredibly dangerous place” in the months before the 2024 presidential election.” And here we are today, with another presidential candidate shot at.Signs of the danger have plainly escalated. The Jan. 6, 2021, siege of the U.S. Capitol was ...
