No you don't. If you wan't to protest politicians, you go to capitol hill or your local political hub.
If you want to protest police, you do the same. You don't obstruct police work.
Using the national anthem and flag at an non-international athletic event for commercial gain is worse according to American law than someone taking a knee, but noone bats an eye.
You're as bad as the politicians you disregard Pete, you can't just pick and choose what offends you more, because it finds your agenda.
You've obviously, completely missed the point here Pete.
