Given President Trump's claim of many rapist Mexicans and other type of criminal Mexicans in the United States and therefore his loose claim that all Mexicans should be shipped out, it may pay to consider some thoughts of Murray Rothbard in The Ethics of Liberty:
Perhaps the largest criminal class today in the United States is teenage black males. The risk of this class committing a crime is far greater than any other age, gender, or color group. Why not, then, lock up all teenage black males until they are old enough for the risk to diminish?...
I submit that there is only one why not, and this should be no news to libertarians who presumably believe in the inalienable individual rights; namely that no one has the right to coerce anyone not himself directly engaged in an overt act of aggression against rights. Any loosening of this criterion, to include coercion against remote "risks," is to sanction impermissible aggression against the rights of others. Any loosening of this criterion, furthermore, is a passport to unlimited despotism. Any state founded on these principles has been conceived, not immaculately (i.e., without interfering with anyone's rights), but by a savage act of rape.-RW
I should add that in a Private Property Society this type of problem wouldn't exist. You just set your own rules for your property.
