I chuckled at his indignance over how these things are legal and how easily you can buy them. Chinese will sell you anything to make a buck. It's just business. You can go on Amazon right now and buy a high power 1kW FM transmitter, drop shipped, and set up a flamethrower pirate radio station on a rooftop of your choosing. The cherry on top is they are likely super low quality with crazy spurious emissions.
Of course the FCC will probably be up your ass in half an hour if you tried it; the point is the equipment is readily available in a few clicks, no questions asked.
Don't get me started on the instantly-blind-yourself-and-everyone-else lasers you can buy on eBay (they'll sell you matching counterfeit laser goggles too).
