Arthur killed Grif, which counts as both witness tampering and obstruction of justice, since he lied about having a magic bean that was stolen (did we ever find out WHY?), and that also counts as filing a false police report.

If we live in a town where Emma can arrest Will for ruining her date, then we live in a town where David can arrest Arthur for poisoning a man in the prison cell.
