Irish Mad dog

Why does Ian Paisley look like a man with a mad dog on a leash with regards to the Stormont attack by Loyalist killer Michael Stone ? Why is this a great thing, appearing to be a real moderate by demonstrating to the public what a real Unionist looks like? What a great tactic to insure control of Stormont by implying that he is the only one to claim control of the radical unionist movement?

It seems to be entirely too convenient.
