Four police officers in D.C. have taken their own lives in the months following the Jan. 6 insurrection at the U.S. Capitol.

The U.S Capitol briefly locked down on Monday, and the President-elect Joe Biden's inauguration rehearsal evacuated after a fire alarm in a homeless encampment roughly a mile away sent a plume of smoke into the air and caused security concerns.

After the U.S Capitol attacks and upcoming Biden's inauguration, Donald Trump enraged and isolated himself, which made it difficult to take a glimpse into the President's mindset.
