The Department of Interior has actually put up vehicle barriers to keep the Border Patrol OUT of some DOI controlled lands. Federal Wilderness designation has a significant impact on the ability of the Border Patrol to effectively control crime, due to the numerous restrictions imposed. Our wilderness, national wildlife refuges, monuments and other federal lands along the Arizona border are becoming havens for criminal activity due to drug and human smuggling cartels that now "own" these areas. They understand the severe restrictions on Border Patrol and law enforcement, and it makes these areas very "criminal friendly". We must secure our borders and get law enforcement in these areas.
