I have a feeling perhaps she fought with those who removed her from the gallery. She does not have a right to fight with the police.Of course he has, especially when he has been invited as a guest of the american congress. Nobody here questions that. The issue is that in democracies, dissent is tolerated to a point, and the normal response would be to expell the shouter from the gallery.
Jailing the shouter, if that indeed happened, seems excessive to me.
