Both the 3rd and 4th laws apply explicitly to mind magic, there is no law against binding someone with magic, similarly there should be no law against forcing them to move their arms and legs in certain ways if you do not do it by controlling their mind. Really this comes down to the concept of identity and choice (see Ghost Story).
With the Laws of Magic there is no "spirit of the laws." The laws of magic (in game terms Law Breaker powers and aspect changes) apply because these laws are fundamental to magic in the universe. It has to do wit you believing you have a right to change someones thoughts, or destroy their identity. You either become more inhuman because of your actions, or you don't.
The wardens do not enforce a "spirit of the law," but individual wardens may take a particularly broad view of what constitutes breaking a law. Since without soulgazing someone it is impossible to know weather or not they have actually broken a law (and the wardens often do not soulgaze those they consider warlocks, for their own protection) warden often treat anything resembling law breaking as a violation. If you used magic to move someones arms/legs, it could easily be interpreted as mind magic/lawbreaking when it is not, and the wardens could easily decided to kill you (especially if they only heard about the incident and were not actually there). On the other hand there are wardens, like Harry, who do not take such a broad view of the laws and are more concerned with truth and justice.
