Bel Air Police Officer Matthew Gullion, who is also the pastor of Harvest Community Church, is under internal investigation by the department after he wore his uniform while preaching in three separate videos, including this one posted April 10, on the church's Facebook page. Legal experts say he may have violated the establishment clause of the constitution while doing so. This is him in Rockfield park after responding to a call, with the church's live stream on the left? (Screenshot of Harvest Community Church Facebook page)
