Top law enforcement officials in the Trump administration had a clear message when they announced the arrest of a man charged with placing pipe bombs outside political party headquarters in Washington on Jan. 5, 2021. The message was that people coming to the nation’s capital to attack citizens and institutions of democracy would be held accountable. Yet Justice Department leaders who announced the arrest Thursday were silent about the violence that had taken place when supporters of President Donald Trump stormed the Capitol and clashed with police on Jan. 6, 2021, one day after the pipe bombs were discovered.
