From my understanding these folks get caught possibly doing something illegal, or get caught under suspicion of being an illegal. But usually they are given a hearing and or trial for anything illegal done in this country and then deported if found guilty. But they only hold them for a certain period of time and then give them the hearing/trial. I think a lot of those who have done something illegal like say murder, rape, or stealing should in fact be held and then get their trial. But I don't agree with holding and detaining for months on end without trial or hearing of any sort.
I also think that this current administration is looking to buy time, and states are getting overwhelmed with holding so many people. They aren't set up to hold that many people for long periods.
In addition a lot of these folks who are coming here in droves apparently are children, many are very young, and they are traveling many countries to get here. Some from Ecuador and other countries not just Mexico. My question is, why is there this huge flux all of the sudden? Who is coordinating all these children's travels here? I think there is much more going on than just promise of being in a free country.
