I suggest reading Turn Coat, where Anastasia explains, that the laws of magic aren't there to enforce justice in general. They are in place only to limit power.
In a hypothetical situation:
A wizard owns a company. But his profit is low, because a vanilla competitor exists nearby. So the wizard is, according to the laws of magic, free to drop by, unnoticed, at his competitor's place of business and cause property damage for which he can't be blamed by vanilla justice and won't be pursued for by supernatural nations, unless the target has their protection. As long as he doesn't kill anyone or twists anyone's mind, no problem.
