Phoenix ? A seventh challenge to Arizona’s tough new immigration crackdown says training materials designed to teach police officers how to enforce the law give “vague and ill-defined factors” as reasons to question someone’s legal status.

Officers aren’t supposed to use a person’s race to determine whether there’s reasonable suspicion they’re in the country illegally.

But the lawsuit, filed Friday in federal court, says the training materials developed by state police bosses allow officers to rely on things like whether a person speaks poor English, looks nervous or is traveling in an overcrowded vehicle. They can also take into account whether someone is wearing several layers of clothing in a hot climate, or hanging out in an area where illegal immigrants are known to look for work.

That will lead to “widespread” racial profiling of Hispanics, the lawsuit says.
