Talk is cheap. I'm glad that the current holder of the office (or someone writing for him) is willing to step out and say the obvious - bad things can happen when science places tools in the hands of unethical people. But we know this; so why state the obvious in a national address, anyway? Unfortunately, based on this administration's developing record for saying one thing and doing whatever the hell they please, I can't help but wonder if Mr. Bush's people are truly concerned with discrimination based on genetic testing, or if they are using this argument to build a case against genetic research for other reasons.
Anyone can use the "what might happen" form of argument against almost anything. If you don't like the Star Wars missile defense you might point out a lot of bad "what might happens" if we continue to pump money in that direction. I consider it a specious, self-serving and pointless form of political posturing, even in the rare case that the practitioner and I agree.
