Is there any evidence of such?
A floating formerly healthy young man in the prime of his life along a smuggling route is a clue.
There have been a couple of reports (fairly) recently of illegals trying to pull agents into water when they tried to aprehend them. I tried search but couldn't come up with the right keywords.
when it does happen, just like laredo nuevo and monterrey, they’ll just use the jihad head approach, then we will know that we have lost the war
