"Politics is the skilled use of blunt objects." - Lester Pearson
Yes,it sounds good but the opposition still will do nothing to force staffers to appear even though they could bring a motion of contempt as well as have no-shows arrested. But will they do something? No. They are just as full of hot air as Minister Barid is.
I think its a little more complex than that, kirby. To declare open season on the government is to set yourself up for a mistake and a wild counterattack; the Opposition can only do so much to keep it from devolving into yet another battle between Parliament and the executive/Conservative cronies. We don't need these constantly. It takes time and energy, aye.
