Why would they report this kind of info, including the informant’s name? Do they want him murdered in prison before any trial?
Do you recollect they put Ramos and Compeon in general population in prison where at least one of them was severely beaten before they put in in solitary confinement. They KNEW he was a border patrol agent, but did it anyway. When the government goes out of its way to protect a drug runner, they do it to make sure no other border patrol agent makes the same mistake of "doing his job."
