Lots has been discussed about Trump's 21 gun salute, 3 seconds apart, vs the video of Biden's 10 gun salute, 10 seconds apart. But I went to compare the last 4 presidents and guess what?
Bush: 21 gun salute IMMEDIATELY FOLLOWING HIS OATH
Obama: 21 gun salute IMMEDIATELY FOLLOWING HIS OATH
Trump: 21 gun salute IMMEDIATELY FOLLOWING HIS OATH
Biden: No salute after oath
^ Listen, no salute, no guns going off like with the others.
The video passing of the 10 gun salute is at Arlington well after the oath, which diverges not just in it's nature, but it's timing. Military broke tradition and did not salute Biden after his oath. Infer what is obvious from that.
Here is Regan's inauguration, all queued up
You can't hear the guns too well, but they show them
Here is Carter's inauguration, all queued up
You can rarely hear them, but they are there. TV cameras weren't set up to show them this far back it seems
Here is Nixon's inauguration, all queued up
You can hear the guns, they show the guns
(Yo Carter, why weren't the guns televised in your inauguration my dude?)
LBJ & Kennedy are harder
But despite TV not being what it later became, Kennedy got the salute, if you believe this auction for a mortar shell casing from his inauguration.

There's a reason for everything the military does, especially when it comes to ceremony. You don't just move the salute to the following day, or hold it off site. The inauguration isn't a wedding where you debate on having the reception before or after. Garth Brooks can sing, but where military protocol has a say, it's explicit.
If Biden was entitled to it, he would have received it. If he was not entitled, he would not be PERMITTED IT. I wish we had a functioning press to ask these sorts of questions.
