The reasoning is that we don't know if the children are being kidnapped or not (this was happening during the Obama years), but I don't know enough to know if it's being handled well.
I find human trafficking to be a greater offense than fishing without a license, and that doesn't work as an analogy. Do you really want law enforcement looking the other way on this issue?
If you're smuggling children across the border should the children be in the same cell as the trafficker? Of course not. I'm all for making this process as fast as possible, though.
It's a simple calculus: you get caught for fishing without a license, should your children be taken away from you?
