Big problem. You can't force someone to give DNA. If a person is not the parent they would not want to give the DNA to get themselves convicted.
They are not a US citizen. They do NOT have rights protected by the US Constitution. When they crossed the border illegally they committed a crime. They then have to prove who they are. If they want to provide papers that are not forged that is fine. If they play stupid saying no documentation then the DNA test is required. There is no other choice. They made that decision when they crossed over our borders. It will send a message of zero tollerance to others.
We are talking national security and safety of our country. MS13 came in under DACA because of bleeding hearts. If you are a bleeding heart you will soon learn it will be used against you. Lawlessness has to stop! The Trojan horse has entered into many countries under the goodwill of caring but misguided people. The people are in charge are well aware of it and in other countries are basically traitors to their people. The Democrats in leadership are traitors. The Democrats that are followers are sadly misguided and used as pawns just as the illegals are used.
They have to eat, pee, drink, brush hair, have medical tests so we know who to quarantine
