Is the crime of theft committed if it was proven to be an accident? For example you moved houses and somehow accidentally took your neighbors lawnmower? What if you returned it quickly, what if they asked you if you had it and you first said no? I'm interested in things that are generally under a few hundred dollars.
Maybe a simpler example is you were transporting boxes for your work and realized you had forgotten to take one out of the car. Is this considered theft or must it have been proven intentional?
Does the burden of proof lay on the plaintiff to show it was on purpose, or the defendant to show it was by accident?
