DHS CBP will occasionally share numbers of entries....and occasionally, these will include the number of "got aways" they know about. They can only estimate the number they don't know about.
Often, foreign press can be helpful on this particular issue since they typically have no stake in supporting a red or blue narratives. Other sources include social media, where young women or families are given discounts if they post selfies with them smiling and describing the process as easy....to lure more people into this system of abuse.
Then there's common sense....I don't expect you to think like a Mexican cartel
@wing2000 but have I said anything unreasonable? I can probably find some official explaining this to a reporter....but would you believe him?
I'd be more inclined to post such evidence if people weren't pretending that I'm making some wild claim by saying that people who supported a candidate and his policies are partly responsible for the consequences. We're talking about the same group who believe taking money out of my pocket and giving it to someone else.....is justice because "slavery".
If they can make a stretch in reality like that, but can't understand the consequences of their own votes.....well, it doesn't exactly restore one's faith in democracy.
