I fear you are correctOh, believe me - I've got "plug-ins" on the TX Border - and yeah, the porousity is simply unbelievable. My point was that to repeat untrue stories lessens our validity on the ones that ARE true, but unreported - and there's WAY too many of them. The cartels have begun their media intimidation well into the US, with threats against journalists that if they report a story, they or their family won't survive - and the journalists are running for cover.
It IS bad out there - and it's going to get worse, because the corruption within the Mexican LEO community is so pervasive that it's going to take a bloodbath beyond anything we'd believe to even stand a chance of stopping it.
