“as those won’t be overheard so much. “
Get real, they can be heard from miles away. The military and intelligence agencies maintains vehicles for intercepting VHF/UHF transmissions, and aircraft, and drones, and satellites, and listening stations. Hell, you can’t trigger the mic without at least multiple devices being able to hear you.
As I said, you can try to hide anything and everything about yourself but that, alone, can tell “them” much about you. The viewpoint is this, unless “they” can prove you are not a threat then you are a threat. If you fit a basic profile, male/age/etc, then you are a threat unless proven otherwise. Hide? Not a chance. You had better be prepared to confront any attackers head on and not hope you can hide under the bed screaming “But I didn’t use a credit card! dammit!”
Dang, some folks sure have their panties in a wad today. Guess you couldn’t be bothered to read what you quoted before trying to spin it. I said the short range ones wouldn’t be overheard “so much” as the longer range. Is everyone who’s listening military intelligence? Huh? No, I didn’t think so. You don’t think the libs down the road won’t be listening? Do you really think the average zombie would have drones and satellites monitoring your every move? No, YOU get real and quit spinning posts.
