A witch-hunt indicates that a mob of people is trying to burn an innocent person. Bruce Wagner is not an innocent person. At least not according to a court of law.
a mob of people is not a court of law
And yet, a court of law clearly
is a mob of people.

But not a mob of people selected by themselves

You won't hear me say Bruce Wagner is innocent.
But I don't think we are the people to "hang 'm high".
