You also can't keep all water off a ship. Doesn't mean you don't try to make it as watertight as you can.
Deporting over a million people a year is a huge operation.
NO administration will do more. Our resources are stretched too thin.
Why don't you concentrate your fire on the Party of Treason officials who organize these demonstrations and who REFUSE to assist federal authorities in immigration matters? Or Catholic churches which provide sanctuary and aid rather than attack the authorities who are deporting 100,000 per MONTH?
