The Presidential Salute is 4 guns and 21 shots in rapid succession.
Biden got 3 guns and a 10 second pause between shots fired.
Biden got the salute reserved for Foreign Dignitaries.
Now …. Are we to believe the military all of a sudden forgot which gun-salute to give an incoming President? I don’t think so.
The odds of that are near zero.
What we saw was a very clear sign.
It also wasn't immediately following the inauguration, it was at Arlington Cemetery iirc.
Symbolism: the death of our nation/republic by the guns at Arlington National Cemetery. Biden being sworn in ten minutes before standard inauguration time-illegal or fake President.
