I can imagine a public or private entity that goes around and fines people that do not switch off bad equipment and fine the manufacturer (or bar them from doing business in the country).
Ham Radio operators or clubs will often track down rogue radio operators or significant sources of noise, like arcing power lines and report the source to the power company or FCC.
The manufacturer is often nearly impossible to find, and they're not doing business in the country, some enterprising ebay power seller is.
Baby monitors, wireless yard cameras etc are often absolute garbage from an RF point of view, and sold with brand names such as "best for baby". Good luck trying to nail that company.
The FCC's mandate isn't to stop everyone everywhere in the world from producing crap $5 baby monitors that spew noise on the whole spectrum. Their mandate is to keep those crap baby monitors out of the US and off US markets. Which they can do relatively easily; even if the manufacturer is hiding behind seven proxies, twelve shell companies and sourcing from two dozen countries, those baby monitors still had to get into the US at a particular port of entry, had to be sold by someone who had the ability to take payments from and arrange delivery to people in the US, etc., and that's going to point to someone the FCC can happily issue big fines to, discouraging them from continuing to import/sell the devices.
There are literally dozens of sites you can buy cell jammers from, pay with PayPal and get it in the mail a few weeks later. The mail is really not checked for this kind of violation very often.
Who are you going to sue if I order a cell jammer from a China or Hong Kong based company and your own governmental postal service delivers it to me? How about if it's just a crappy or malfunctioning device that leaks and I have no knowledge of it?
It's a very difficult thing to police... almost approaching war on drugs territory.
The fine and jail time apply to the person operating the jammer. By the way, these "dozens of sites" are all too happy to turn over purchase records to law enforcement if asked.
As for "it's a very difficult thing to police", a jammer is a transmitter, one that's powerful enough to drown out the signals it's designed to jam. Turning one on is like turning on a giant flashing billboard saying "ARREST ME" over your head; it's easy to follow the jamming signal back to the source with the right equipment, which, of course, the FCC and similar agencies have plenty of.
