We only have limited resources, in this area. Hence this voter, wants those scarce resources utilized first to be rid of terrorists, and criminals.
Going after some otherwise law-abiding person, just to prove the point we can, is not the most productive use of those resources.
We have had several terror attacks, by people that authorities supposedly were aware of, and watching to some degree. Use limited resources on this priority.
And we have criminals being released from jail/prison in sanctuary cities. Use limited resources there as well.
Only when these two areas are fully under control, is there need to address the young people, by no fault of their own, are present in the US.
