You can have perfect crypto on your devices, and great operations, and your messages can still be intercepted several ways. The feds are almost never in a rush. If they want you, they'll get you. If they want you enough, they'll sit in a coffee shop they know you frequent with a high zoom camera ready to read your encrypted texts from across the room. Or they'll bug your car and listen in to your properly encrypted phone calls. Or they'll intercept a package and add some spy gear. They won't do this to bust some street level meth dealer. But, if you're suspected of something like posting state secrets in a Minecraft server? You betcha. They'll follow you everywhere.
