Yeah, they were there to heckle a politician. We have a Constitution and Bill of Rights in this country, we are allowed to do that.
Take your crap somewheres else bub, like kindergarten, post haste.
So, you disagree with being allowed to speak out against politicians you don't like. Are you a communist or something? Because AMERICANS understand the concept of free speech.
The First Amendment states that the people have a right to assemble peacefully
There is no constitutional right to prevent someone else from express that right. Get real.
Heckling, to the point of disrupting a lawful assembly or preventing other people from speaking, is illegal. It has been litigated many times. Usually comes with a conviction for disorderly conduct.
I heckled B. Clinton once but I did not prevent him from speaking so it was fine. He and the crowd heard me and my cohorts but the event was not disrupted.
Now, if you want to engage in civil disobedience, which is a tradition in American politics, be my guest. BUT you can and should be arrested and you have to be willing to face the consequences. You have to be willing to prevent someone else from exercising their constitutional rights though.
