My personal rant on this is that why can the government use encryption and we can't? Is AES allowed on ham bands right now? DMR and dPMR come to mind, but dPMR is only alloed in the EU and DMR you need a license, don't you? On the software side you had the Lavabit situation. The feds demand the encryption keys to the encrypted E-mail. Lavabit said F it and shut down. Now you have Truecrypt that shut down possibility a Lavabit BS thing. The only form of radio encryption I'm allowed which pretty much suxx is Motorola DTR's and voice inversion on family radio. But I don't think your allowed to use voice inversion on a FRS radio anyway, but manufactures make it. There are cheap China radios that use voice inversion, but you need a license to use those frequencies, Legalizing dPMR would be great, but the encryption is weak.
So the feds can and want to hear you, see your E-mail and know everything you do, but not the other way around. The founding fathers are rolling in their graves! The police even buy stingrays to hear your cell phone calls.
