Even though he's more of a Dr. Who fan, my boyfriend has seen B7, and made what I thought was a good point. If the Federation had only one limiter, or only a few, why not implant it in Blake, whose violent impulses were likely to cause a lot more damage than Gan's?
And, by the way, why did the Federation have to go to the trouble of actually conditioning kids to believe that they were molested by Blake? That would make sense if there were a well-publicized show trial, where TV clips of the tearful child victims might lead to widespread revulsion against Blake. (Although why anyone would then be deterred from political subversion because of Blake's personal failings...) But in fact, the fabricated evidence was simply input into the prosecution marble that went into the Justice Machine. Perhaps they could have fabricated evidence that didn't have inconsistencies for Tel Varon to spot if they didn't have to waste time conditioning the "victims."
