I agree with #7
I looked at the piture. Where is the razor wire across the top of that fence. Any half physical human could climb over that.
And, believe it or not, that is the “good part” of the fence. Most of it around there is either non-existent, or some wooden fence posts. I don’t necessarily believe that a fence across the entire southern border is the answer — it turns our formerly beautiful desert areas into even uglier war zones — but it sure helped the San Diego sector when they put up a REAL fence.
