Honestly, they should put some sort of glass box around Joe Biden. If they don't take extra precautions very seriously, I think the chance someone tries to shoot Joe Biden in his first 100 days or so is quite high
Uh, if anything, they're going overboard on protections. Downtown DC and the mall is probably the most secure place on earth right now. I'm really not too concerned.
I hope you're right, I always worry about this sort of stuff too much.
Overall though, Biden should try to avoid situations where he's out in the open as much as possible during his first 100 days because I think there's a pretty decent chance he's shot. I worry that somehow something stupid will happen where some Trump loyalists will shoot some Democratic Senator from a red state and a Republican replaces them and we lose the Senate.
