Powell: Security Fences Don't Work

Colin Powell says that border fences along the US-Mexico border won't work (sort of like his foreign policy approach).

"The Berlin Wall did not work perfectly and the wall that the Israelis are putting up is not going to work perfectly," Powell said. "So, a wall alone is not the answer."

Of course a fence isn't perfect - but if you want a 90-95% reduction in people coming across, a fence is a good place to start. If you don't want a reduction, then a fence is obviously not a place to start.
