if they were mutants naturally some would be good some would be bad just like "normal humans" measures would have to be taken to make sure "bad mutants" didn't take over. passing laws wouldn't do sh*t if you could turn to metal, controll minds or scream so loud you could break steal or etc, a "your not allowed to use your powers to hurt people law" would stop you if you wanted to use your powers to hurt. I believe education is the key..if "normal child" and "mutant child learn to consist as kids...they should be able to do so as adults....for the most part..but I sugguest having a sentinal program up...just in case.
