I can't wrap my head around your liberty for illegals crap. You're conflating citizens with criminals
Do you really believe that the power-hungry, out-of-control government will stop with illegals? You think it is wise to grant the authority of the federal government (or any government) to strip ANYONE of all property rights?
Is it ever wise to grant a government authority to do things that no free individuals would have?
Government is like fire. When used properly, it serves a much-needed purpose. But, if you fail to keep fire contained to a very limited area and size, it will burn everything down and kill everyone/thing in its path.
There is no equilibrium when it comes to control over government. If we are not constantly reducing and constraining government, our rights are being reduced and constrained.
