Terry Harrington spoke to Coe College students on Tuesday, recounting how he was wrongly convicted in the 1977 shooting death of a Council Bluffs security guard when he was a teenager.

WATERLOO, Iowa (AP) — Officials in Waterloo have approved a measure banning the city and many businesses from asking about applicants’ criminal records in early stages of the hiring process. The Waterloo-Cedar Falls Courier reports the City Council on Monday approved a so-called “ban-the-box” ordinance. It doesn’t let employers ask about an applicant’s criminal history until after making a conditional job offer. The measure is intended to ensure people with criminal convictions get a fair chance of getting jobs.
