You never know how the product of research is going to be used. How do you imagine laws trying to solve that?

Laws? We don't need laws. We need researchers (and their underwriters) with ethics, foresigh, and a sense of responsibility and morals.

The standard cop out "Oh. I'm / we're responsible for how X is used" is irresponsible. History shows us that.

We don't need laws. We simply need accountablity. It's not rocket science ;)

Maybe we did know but were made to forget.
