I think the purpose was to prevent any kind of protests against Biden during his inauguration, and obviously, this is concerning.
- two weeks earlier the Capital was attacked, for the first time since the British attacked it, in attempt to stop Biden from becoming president.
- they still haven't caught whoever left the pipe bombs
- there has been tons of online chatter planning similar attacks
- Biden, Harris, Obama, Bush, Clintons, Pelosi - all the main villains of every qanon conspiracy theory all in the same place at the same time
Don't worry, there will be plenty of opportunity for people to protest whatever they want.
