@revelette1,
People who come from war zone areas or places of great violence can apply for asylum, that is their legal right. Those people by definition are not illegal immigrants and should not be imprisoned nor flown back at least until after their asylum request is rejected, if it is rejected. If they must be held somewhere while the asylum decision is made there is no reason to separate the parents from the children.
If we send those who are not asylum seekers back to whatever country they came from in daily government plane flights, it would be far more humane and cheaper than this incredibly horrible situation that has emerged. Of course, we could always revert back to what existed before Trump instituted the zero-tolerance policy, which was not so terrible either. After all was said and done, there was no border crosssing crisis when Trump took office, illegal border crossing was declining actually.
