Criminals perpetually update their technologies to incorporate the very latest emerging technologies into their modus operandi. They have evolved well beyond the days when they were the first on the street carrying pagers and using five-pound cell phones to send coded messages to one another. Today, they are building their own nationwide encrypted cellular radio telecommunications systems, like those employed by the narco-cartels of Mexico. Consider for a moment the sophistication required to establish such a fully functioning encrypted nationwide communications network - an amazing feat, especially because many Americans still can't get a decent mobile phone signal most of the time.
