Sounds very likely they had hoped to trap him on the long country road and use that time-worn claim he was shot because he seemed to be going for a weapon.
What a treasure Tex Harris was to the diplomatic corps. He surely put ordinary right-wing diplomats to shame, didn't he? You wouldn't know they all worked for the same State Department of the same country.
Had to notice his long-horn tie clasp (he needed the string tie to hold his clasp in place) immediately upon seeing his picture, and the picture in the video of his car shows his pride in his Texas heritage manifested also in a humongous car hood ornament! He wouldn't have been hard to spot driving anywhere.
Sounds as if he became very deeply involved in learning what the dictatorship's activities were, and worked as hard as he could within his position to help the struggle of the victims.
Had never seen that still photograph of a poor mother trying to beg soldiers to not harm her family member they were rushing off to torture and worse. The moment you see it, you feel overwhelmed by her anguish and it makes what they experienced that much more real than in simply reading about it. It reminds you this scene from hell played out so far over 30,000 times within a few years.
Found a photo of Tex Harris with two other Princeton grads. attending a reunion, thought it was pretty funny, considering!

Thank you for the video. It was excellent hearing his harrowing experience, and the moment of staring reality in the face at close range.
