First off I'm pretty sure that the Lawbreaker stunts and the laws of magic only apply to spells, if someone has supernatural strength and sticks a sword in someone they do not get lawbreaker. Not to mention thwe fact that lawbreaker stunts are gained because you completely believe in the action. But even assuming that you are right lets look at those laws
if you do it to a human i at least would hit you with lawbreaker First [as appropriate] , Second [nearly always], Third [especially if taking skills] and Fifth [ if you use the power on corpses]
1st: probably not as you most likely wouldn't kill them via this power, you might kill them before or after this power but I don't think that this power itself does any damage to them.
2nd: You really aren't transforming another person. That is meant to be warping their body and destroying thier mind, this power does neither.
3rd: The problem I see with this law is that you don't mess with their thoughts, but you do copy their skills, so this is really an ST call.
5th: It is demonstrated in the books that imprints can be read off of a dead body without breaking the laws, so I'd say if you eat a corpse to gain its' power that wouldn't grant a lawbreaker.
All that being said I strongly disagree with giving lawbreaker to anyone who did not cast spells.
