The inauguration is unnecessary.
Trump needs to take the oath in front of an official authorized to administer oaths this weekend. He becomes President automatically at noon EST on Monday, and at the same time becomes commander in chief of the Army and the Navy.
If it’s safe to have a ceremony which ILLUSTRATES the transfer of power, fine, have it. But don’t take chances for a photo op.
Trust me, I get both of your concerns. Thing is, Americans do like their ‘pomp and circumstance’. It’s tradition, and that’s why they have the ceremony.
It’s only in recent times that, with increased communications and the increased ability for the public to see and hear just how much certain people don’t like (read “utterly loathe’) people like President Trump, that our concerns with his safety are at the forefront.
