This is why the suggestions that, THE MAN, is watching us all the time completely fall apart. They don't have the manpower to do it. On an average day I generate 30 to 50 text messages, 15 to 25 phone calls, 10 to 20 e-mails, and 50 to 100 internet based communications. That's 105 to 195 discreet communications per day. I know I've had prodigious days that pushed that probably over 400. That's just one person. There are plenty of text addicts that might spout off 100+ texts a day, along with Tweets, Facebook, etc. Some people probably blow out 500 or more discreet communications per day. A lot in fact. How do you even begin to keep up with that? Much less deal with the context surrounding the messages which is often critical.Said individual clearly has no concept of the type of manpower it would take to accomplish what he is suggesting.
That plus massive data storage, exabytes by the thousands, communications lines the likes of which aren't even in existence and so on. And that's just to start the sifting process. After that the hundreds of thousands of communications that take place, just within this country, that need a human touch happen. How many tens of thousands of analysts do you think they have dedicated to this process? Mind you, this is just to keep tabs on our own citizens for reasons that are usually ill defined if you can even pick them out of the cloud of pot smoke surrounding their proponents. Never mind what it would take to keep tabs on the people who are the actual threats to the country.All they'd really need is a couple (hundred?) supercomputers and some software and search buzzwords.
The buzzwords thing is even more pointless in that the kind of words you are hunting for are now day to day talk of completely harmless people. Bomb, Al-Queda, airline, terrorism, assault rifle, border security, back-scatter x-ray, ANFO, pretty much any potential buzzword you can come up with is already in the general parlance and used by people constantly. And if someone wants to avoid a buzzword detector then it's entirely possible to talk in code if you need to. You don't talk about the dirty bomb you're going to set off down town. You ask if grandma's laundry has been delivered.
And in the end there's the fact that it's utterly pointless to do all this since 99.9% of all American's lives are incredibly boring and uninteresting and keeping tabs on them is a total waste of time.
