If he is being framed of terrorism charges, and he is going to a terrorism related court (is there such a thing?), then it is good news for musharaff. Because those charges will not hold water. There are very real and very serious cases that he should be tried for, like subverting the judiciary, and suspending the constitution. If those are being dubbed as "terrorism" instead of the right words, then his defence lawyers will easliiy beat the case.
While all musharaff supporters here seem to be upset that he is being charged with terrorism, I think you are all missing the point. That could be a way of setting him free, by misphrasing the crimes he commited.
If a rapist is taken to court and the prosecution charges him with murder instead of rape, he will easily beat the case in court because they cant prove that he murdered anybody.
