With the unreliability of GEBE, I would think a back-up generator would be in order. I would also think an electric fence could easily be disabled and would be out of service many times. They (electric fences) work well for livestock but they (the livestock) are probably smarter than some of the humans this fence would be protecting.

Personally, I don't have a problem with electric, barbed wire or even razor wire but there is only so much than can be done to protect people from themselves and the chances they take.
