The Texas Observer has an important article out on Ken Merritt, who was forced out of the US Fish and Wildlife Service for resisting harmful and ineffective border walls on National Wildlife Refuges in south Texas.
Here in Arizona, wildlife refuge managers are concerned about DHS plans for Boeing's giant surveillance towers, which have been shown to not work, in protected national wilderness.
People, wildlife and habitat are suffering as the feds shamefully build a new 'Berlin wall' against a friendly neighbor and essential economic trading partner. The only thing Bush's border walls won't stop is people seeking a better life for their families.
Wildlife-friendly vehicle barriers, which are proven effective, are a much better option for controlling illegal border traffic.
Border walls are a made-in-DC 'do something' project for politicians and bureaucrats to point to. As Bush/Cheney/Chertoff and others point, to try to deflect criticism away from their failures, people and wildlife die.
America desperately needs holistic immigration reform to allow people to legally cross at ports of entry to work and visit family in the US, and to stop the deaths, suffering and damaging, failed militarization of our southern border.
