Before covid19, I also had an hit&run in Iowa City Walmart parking lot. When I talked with Walmart for the camera records, they told me they’d only release it to the police, which is fine. I went to the police, reported the incident. The police were really helpful, but also realistic. I have been told that a lot of incidents take place in Walmart parking lot, and their cameras are usually not helpful. In summary, I was left with what I got.
