(Disclaimer: I think this measure is both inhumane and ineffective, and I’m not defending it in any way)

Lots of time the people that are scheduled to be deported don’t have any documentation to prove where they are from, and even in the cases where they have their original countries don’t accept them back, which makes it impossible to deport them.

But again, while there’s no easy solution to the problem, IMO sweeping the problem under the rug is not even close to one.
