I’ve been having trouble finding equivalent statutes in any jurisdiction, except the ones already posted (then again, I’m lazy).
Passive cable theft isn’t a crime per se, at least not at all what the cable companies contemplate. Passivity implies lack of intent to steal cable, as demonstrated by the OP. Now that he knows, is he going to get paid for his time auditing the cable company(ies)'s records? To continue receiving cable in this fashion may not be moral, but it’s not clear that it’s illegal.
IMHO, neither the Fed or the MS law cited is particularly good law. It does not account for the special circumstances (the technology inherent within cable tv) or lack of proactive duties (all the stories of doing nothing when it comes to disconnect) or the history of the cable companies (particularly the monopolistic environment in which they thrive). Note: these loosely based ideas are more grumblings than any real anaylsis, however:
The law does not contemplate other real life circumstances:
a) situations where people call the cable company to disconnect, and it never happens. Should the cable companies now have the full force of the law, years down the road to extort maximum fines and penalties?
b) situations in multi-unit/single unit dwellings where antennae access and cable access are one and the same? I’ve known tons of people, particularly in the city, but this happened at my folks’ home, too, where cable is running through the antennae, and by using the antennae to get publicly broadcasted channels, you get cable for free. My parents switched over to satellite, called to cancel, and it was never shut off. Then, the local cable company got bought out, and they started getting better, higher tiered service. Now, my dad can watch satellite, and tape my mom’s shows at the same time.
How is the OP’s situation different from someone throwing seed on your fertile soil, and telling you that if you reap what you sow, you have to pay the man?
How is the OP’s situation different when a salmon farm’s fish swim into his pond or lake?
Or any situation where something is left or delivered to the wrong property, but for the act of delivery, it cannot be recovered? Is the receiver automatically forced into a contract?
In other words, the law seems to be too in favor of the cable companies.
I don’t have an answer, just opinion and conjecture.
