Having seen General Keane while he was the Army’s vice-chief of staff and heard him speak several times, I do trust him.
Those who invoke Posse Comitatus as a reason not to defend our border do so because they're looking for an excuse not to defend the border at all. Their claims are based on a complete distortion of what Posse Comitatus means (i.e. not using the military as a police force). It's just as specious an argument as the idiotic refrain we keep on hearing about illegal immigrants: "Well, we can't deport them all [so why bother deporting any of them]."
