Bah, when I was traveling around US for a few months, more than once activist groups stopped me and tried to force me to listen to their agenda. Sometimes it was about veterans, sometimes about how only their own particular brand of Christianity will save my soul and so on.
If that is a crime, we'd have to jail all traveling salesmen, Jehovas Witnesses, PETA activists.
Based on the article, there was no violence or threat of violence, so no harm done.
