The 2020 Presidential Election was unique in the way that there was essentially no part of the process that the public took for granted.
While the practice of mail-in and absentee voting, the state certification of electoral results, and the joint session of Congress that confirms these results are normally not considered particularly noteworthy aspects of an election, all were the subject of great public anxiety this time around as it seemed unclear whether voters could do their civic duty safely and whether their will would be respected.
So while a president's inauguration can be a matter of widespread excitement depending on who they are, the fact that one took place at all this year was a cause for celebration.
With that in mind, it seems fitting that one Capitol Police officer should take an important role in the inauguration since we may not have ever seen it without him.
