OpenPoliceData is a Python library which serves as an access point to hundreds of valuable datasets. We've added them to our database before, but it's been a while since we synced.

Requirements

• We should periodically (monthly?) check OPD for new sources and submit them to our database via API
• example from @sowdm at OPD
