Yes! Finally!
Not so fast, what does the state of Texas plan to do with them?
They have no authority to send them back to Mexico if they refuse to go voluntary. Mexico will not take back anyone that is not a Mexican citizen.
If they turn them over to DHS they will just release them.
So the only thing this provides for is incarceration. That's going to be really expensive and wile it may give a added level of deterrence it really does nothing to solve the problem.
The best that can be hoped for is that the smugglers move their operation out of Texas to other states but since they're well established in the border towns that is unlikely.
Sorry to be the conveyor of sad news.
