This seems like a valid, if hyperbolic, point to me. I think that one could make a plausible argument that one of the most basic implications of the principle of rule of law is that, at least where the police are concerned, the ends don't justify the means. Allowing them to behave otherwise isn't a slippery slope that leads to rampant abuse of power; it's a dead drop.
