Ariz. sheriff's safety reviewed after Dobbs scare

The security of an Arizona sheriff who has aggressively cracked down on illegal immigration is under review after a shooting scare involving CNN commentator Lou Dobbs.

A bullet struck Dobbs' New Jersey home on Oct. 5. On his radio show this week, Dobbs connected the gunshot to his advocacy for a crackdown on illegal immigration.

Authorities in New Jersey say they're still investigating and have not yet identified a suspect. They noted that small-game hunting season is under way.

Maricopa County sheriff's spokesman Ryan Lee says the agency is concerned for Sheriff Joe Arpaio's safety considering that both Arpaio and Dobbs are extremely vocal about their stance on illegal immigration.

Lee also points to protests that Arpaio's television and newspaper interviews have incited.

Arpaio's security detail is looking at the current level of security provided to the sheriff and whether more security is now warranted.
