I just noticed I was mentioned here and have to weigh in now:
Viperscale covers it all below as far as I can see, but I'd like to point out that you're being absurd.
The crimes you're speaking of are committed by citizens as well, by the logic presented, we should just ship every person out of the country, including ourselves, because we can't tell which people are murderers and rapists.
It just doesn't make sense.
Becoming a citizen =/= immunity from rape and murder charges, no matter how many punctuation marks and capital letters you use.
