I want to open a business: a spy agency. Detectives, if you prefer.
Learn your competitor’s business secrets! Find out if your spouse is cheating! Think there’s a conspiracy? We can find out!
Here’s how it will work. My agents will (discretely, of course) follow around the target individual(s) in public areas, such as restaurants, airplanes, and stores. They will (discretely) eavesdrop when the target individual is talking on the phone.
It’s just that easy. People talk way too loud, and we all know how often we’ve heard people say things in public that we weren’t meant to hear. If my agents listened persistently, think how much they could learn.
Espionage. Perfectly legal.
Easy money. Because people with phones make it just that easy.
