This POS is the reason why we all had to change over from Analog to Digital. They did this because of how the (perfectly fine and working local) EAS was carried out before, with local stations having to have somebody there to physically flip the switches to send out the alerts, thus they could choose not to comply (incurring hefty fines). This way, they have just about enough freedom of choice over it as all of us have: zilch.
As for the reasons they want to be able to grid-lock TV and Radio from wherever and whenever, remotely, and at the 'President's' sole discretion... I don't know (and I for one don't like it one bit). As for why we NEED this... we didn't. The old EAS worked just fine and everybody knows, if something really bad was going to happen which would call for something like this... they (our Government) wouldn't tell us because they don't want us to panic and riot and all the rest of it.
By the way, this NES was a spectacular failure. It was glitched to high hell, entire states didn't get it, had no picture and/or audio or the thing just popped on and off constantly. I for one hope they don't fix it and abandon it... they have entirely too much power over the TV and Radio (and everything else) as it is these days and it's a sure bet that this will not be used as it should be (for emergencies only): they'll find ways to abuse it and even probably start forcing us to watch the President's Addresses and etc.
Or, if they don't like something going on the radio or etc. they can just turn this on and block it out for you (the very same thing they are drooling over doing with the internet). George Orwell's 1984 is happening, folks. The name of this game is called: total control/censorship.
Oh... and I don't recall there being an EAS during or after 9/11 (was sitting right there in front of the TV, not a damn thing about it apart from the news)... a lot of good that did for us then! It'll be the same thing if something like that happened again. No EAS/NES... have to hear it on the news or from somebody calling you. So in conclusion... this was just a huge waste of our dwindling tax dollars and a shameless power grab. Hooray!
