On the other hand it's quite likely that the technology required to build satellites that can observe Earth is remarkably similar to the technology required to build satellites to observe other planets. There's a huge amount of overlap; why wouldn't you want them to do it on Earth first? It'd be cheaper and faster, for a start, along with providing useful information. What's the downside?
The downside is that the shitload of evidence showing climate change is real would grow. That is a downside to Cruz and his minions.
That could be said for any investigative technique. Simpletons said the same about CCTV but now no sane person would deny the benefits of video surveillance. It *works*. It helps *reducing crime*. Those are cold facts. We need to slay that last sacred cow and make another step towards a safer society. And it will happen, whether you want it or not.
I'm not arguing against DNA testing, moron. I'm arguing against compulsory collection of DNA samples from every resident of the country as the OP claimed that there was "absolutely no reason whatsoever to oppose this." If you want to compare to CCTV, that would be equivalent to requiring every resident to have a camera recording their movements 24/7.
