Failure to deal with the problem of immigration will eventually lead to the only possible solution: amnesty granted to all citizens for all crimes related to the purpose of finding, hunting, and eliminating the immigrants.
merely deciding if they are immigrants or not by checking their skin color, will not even meet the threshold of fault to be heard in a courtroom of the law of the world thet could be.
Hence solve the immigration problem now. and keep the world you have now.
