"...while Hain is allowed to skulk behind Parliamentary privilege."

Nope. He used a constitutional right, within the rule of law, that is available to members of both houses and which can be a valuable obstacle to attempts to subvert democracy. There was no skulking. In fact, Hain has been completely open and full-on. In his opinion he was a exposing a known bully and sex pest who he thought needed to be exposed and who he felt was being protected by a bad injunction. So you disagree. Just say you disagree and stop trying to kid us that he is skulking or being cowardly. He has actually stuck his head above the parapet. And, as an aside, just console yourself that he's a far better man than the man he's exposed. But you don't agree. You think that a serial bully and sex pest is more virtuous. Grand.
