When terrorists are declared innocent by courts than why you want to negotiate with them?
When you demand ministries for TTP before negotiations than negotiations doesn't fit.
IMO criminal is criminal otherwise we shall negotiate with every murderer, thief and drug dealer.
There is a term called traitor and they are always locals and constitution does not allow negotiations.
I think your party is already demanding murder of General. Pervaiz Musharraf for imposing emergency, which is only in your definition violation of constitution.
