yeah the police and some branches of the military are working the inauguration-i work at cvs part-time and our usual officers (the store is in a rough neighborhood) have not been there for two weeks in preparation for the weekend's events.
as for the businesses closing it is only fair to the employees who have to struggle with the commute. you would have to leave your house at 4 am to get to work by 9 am. my husband will be off for both monday and tuesday but he has definitely earned it as his job supplies ALL DC bars, clubs, restaurants, military bases and the white house with their alcohol.
