Documented? Not even Tancredo claims that:
""They are reporting that they see people coming through with guns. The concern is that there are people coming through with arms, M-16s, protecting drug carriers," said Mr. Tancredo, who has proposed using National Guard troops at border areas."
"The concern" is hardly the same as documented, and I don't see Tancredo mincing words when it comes to his main, get-out-the-vote pet issue.
Or we can even take the word of those working the border:
""These situations can be very difficult," said Keith Weeks, a patrol agent and vice president of Local 1613 of the National Border Patrol Council in California. "We are outgunned in these instances. They have automatic rifles, and we have handguns." He said that military assistance for drug running in Mexico is "a definite possibility.""A definite possibility" doesn't say documented to me.
If Mexican authorities are chasing a smuggler in the dark, over unmarked terrain, they may inadvertently cross over into US territory.
Each and every one of these incursions, that happen both ways BTW, are discussed at lenght between the two governments, and dealt with at a local level.
I suggest better communications between US and Mexican Border patrols are needed, rather than gunships to start an idiotic and not needed border war.
Are there crooks in the Army? Probably on both sides, but they should not dictate policy, nor be the cause of a border war.
