I love it when people throw out a historical reference when they have no concept of history. The parallels between this and Salem are actually quite legitimate.
The first one accused - Tituba - actually practiced what could certainly be construed as witchcraft. So we'll make Tituba and Salazar on par.
Sarah Osborne - next in line - quite possibly killed her husband, or conspired to do so with her younger lover, She was not ever officially brought up on charges for this though as there was no real evidence so a group of witnesses claimed they had seen her doing other "witchy" things, which she was jailed for. So Galen is Sarah Osborne. (Probably guilty of something but since no one has anything concrete, a preponderance of bizarre allegations will do.)
The nuclear circle then went to people no one really liked and definitely had their faults (Giles Corey for example). Once again there is no physical evidence of an actual crime but a group of people all making allegations of random wrongdoing is sufficient to jail, stone (pressing actually), etc. (Centro = Corey?)
Throughout the whole thing, no one who was beloved in town (oh let's call them Lernard Bagat) or seemed to confess to doing things but only because they were compelled to by the witches (Gara Coucher) ever went down for witchcraft. You could also confess to witchcraft (doping) but so long as you named people who were higher on the hitlist than yourself, you got off scot-free. (What are we at, 14 or so people who have pretty much admitted to something but no one cares about them because it was all Alberto's fault.)
The point of witch hunts is not that they only target innocent people, it's that they use "ends justify the means" mentality. They will and always have nabbed some guilty people, as well as some innocent, as well as many not so innocent but no more guilty than their accusers.
So this is a witch hunt. Like Salem, however, the masses have decided that it is a witch hunt worth having as it could hang (not literally in this case) some people that we are pretty sure are guilty and whom we never really liked anyway.
(I can't decide if Goucher gets to be Mary Sibley or not; it kind of fits.)
