About 200 people gathered in Columbus Saturday to take part in a national demonstration for an ex-NYPD officer.
They rallied for justice near Easton for the rookie officer, Peter Liang.
A jury recently found him guilty of manslaughter.
He was convicted for the killing of a man when his gun accidentally discharged back in November of 2014.
The coalition says Liang is serving as a scapegoat.
Prosecutors said he was reckless.
Liang could face a sentence of up to 15 years.
The protests also took place in cities including New York, Los Angeles, San Diego, San Francisco, Salt Lake City, Seattle, Denver, Houston, Dallas, Detroit, Chicago, Boston, Philadelphia, Washington D.C., Atlanta and Miami among others.
