It's raised pertinent questions: When is it OK to heckle a speaker? Is it a sign of disrespect to the office to heckle an elected official, particularly the president or his wife? It's interesting to read the online comments from this NPR report about the incident.
As for hecklers themselves, they're apparently now all the rage. It even happened recently to government officials who were meeting with Tennessee residents about the First Amendment and the Muslim faith.
