I live in a Commonwealth, Commonwealth of Virginia, the laws are strange to people who don't live here. For instance, if you manage to evade the police and they have no proof that you where actually behind the wheel of the automobile in question, legally they can do nothing even if there is evidence that your vehicle was there. Like the Commonwealth of Kentucky however, you can own a "Machine gun" (any firearm that fires automatically) by registering with the state police. Open carry of firearms is also allowed. This, in contrast to the left coast (West Coast), and specifically, the State of California is like a whole 'nother country. Actually, let me rephrase that, California is like a whole 'nother country no matter which state or commonwealth you compare it too. The problem with the system of States and Commonwealths is that the local government bodies within each state and commonwealth can override the constitutional rights given to us. Example being, California, the second amendment and several other rights they have restricted or suspended.
The point being, the legality of anything is subject to question and legal interpretation by anyone in position to do so. So if your doing something questionable, the thing is not to get caught. IE, guitar amp in the dumpster, or, if you live in the USA, or several other countries you could possibly try to sell it online if it is a model that has any value. Laws vary, noone knows them all, except maybe the Rain Man.
