Maricopa County Sheriff Joe Arpaio is facing more accusations of racial profiling stemming from his ongoing crackdown on illegal immigrants. This time, four U.S. citizens claim they were stopped and mistreated by sheriff's deputies because they are Latino.

In one case, a brother and sister say deputies unnecessarily stopped them in front of their north Phoenix auto-repair shop and forced them out of the car with weapons raised. In another, a husband and wife say sheriff's deputies improperly asked for a Social Security card after they encountered a roadblock while leaving Bartlett Lake with their two children. MORE
