President Donald Trump’s decision to skip President-elect Joe Biden’s Jan. 20 inauguration ceremony disrupts yet another tradition in this country’s historic, peaceful transition of power. In this case, it is a tradition worth breaking to avoid the distraction and potential security risk Trump represents.

Consider Trump’s absence from the transition-of-power formality one more defining moment in an unprecedented era of defining moments for the country. The outgoing president, supported for reelection by some 74 million voters, is reduced to an intrusion. He is a public safety hazard. A cannon so loose he cannot be trusted with basic ceremonial duties.
