When I interview for store clerks, I hand them the application and ask them to fill it out. While they're doing that, I inform them that I will run criminal background checks on them and do a drug screen.
Fully 8 out of 10 hand the application back to me and walk out, calling me a "Racist MF'er." (And that's just the women!)
I ain't no lawyer,but I'll wager that you'd be wise to do exactly the same thing with *all* applicants,lest someone hires a lawyer trained at the Jesse Jackson School of Law and sue you in Federal *and* state court.
