Prosecute for violence and vandalism, and fine them to cover the costs of having to do so.The hecklers veto does not apply.
Should public universities have to spend thousands of dollars for extra security to protect a controversial speaker?
Should municipalities have to spend thousands of dollars for extra security to protect a controversial speaker?
Should the KKK or Ann Coulter be responsible for this cost?
Possibly the Young Republicans that invited Milo?
Or, should there be a blanket suppression, not of speech, but arrest and prosecution for violence and vandalism?
And who foots the bill for that?
