There’s a lot to unpack in the days after an arson attack at the Pennsylvania governor’s mansion.

We should all be able to agree that security around Gov. Josh Shapiro was inexcusably lax given that one of the most notorious recent acts of political violence had taken place in Butler, Pa., during last year’s presidential campaign. It’s hard to fathom how Cody Balmer was able to climb a fence, smash a window, enter the governor’s mansion, use a Molotov cocktail to start a fire and then escape. Police didn’t catch Balmer – he turned himself in.

It’s worth mentioning the ongoing breakdown of social norms that should make intensive security details less necessary instead of more necessary. There are dozens of reasons why we’re seeing an increase in political violence – inflamed political rhetoric by the left and the right, a growth in mental health issues throughout our society, social media and the internet, to name a few – but it’s obvious that security details for those in leadership positions need to be tighter. And this is twice that the State Police has dropped the ball, lest we forget the State Police were leading the detail that botched security for President Donald Trump in Butler, Pa., last fall.

A full investigation is needed into the lapses that allowed Balmer onto the governor’s mansion property. We aren’t going to quickly solve the problems that are leading people to political violence. So the least we can do is tighten security for those in leadership positions at the state and federal levels. That includes, by the way, former federal officials who have seen their security details ended by President Donald Trump.

Political violence isn’t a recent phenomenon. For as many times as we’re told political violence shouldn’t happen here, it’s been happening in the United States for more than a century. There should be no place in our society for the violence we’re seeing, but we should be under no illusion that this will be the last such attack in our state or nation.
