The law is not always equal to morality; or the actions that save the most lives/freedoms.
When the law is followed, there are checks and balances put in place. The possibility of abuse of power is minimized (if not eliminated) when there is absolute law, and accountability, and oversight. Remove those things, and you are left with Section 31, which literally does whatever it wants, when it wants. That is extremely dangerous.
And just because an action that is illegal might save more lives than one which is legal, doesn't make it right. You can't reduce democracy to a numbers game.
