The police and media have worked together and released lots of information on their side framing him as the criminal, but – not unlike https://en.wikipedia.org/wiki/Richard_Jewell – trial by media is not a verdict.

Without actual footage of the scenario, testimony, etc. it’s totally possible that things aren’t what they seem.
