The thing is they shouldn't be allowed to enter the desert in the first place, people that are legally allowed into the desert can buy water at a fair price.
Literally can't tell if this is parody or not. But people are now being prosecuted for supplying water to people in the desert.
If illegal people can't access water in the desert, they won't go to the desert.
I might be wrong but I think that is what the government wants.
No, they'll go through the desert and some of them and their children will die. And this will be on the heads of those preventing them from having water.
