Why would the Enfield Police be assisting the Aircraft Owners and Pilots Association all over town? Saw another one in todays shift log. Does AOPA also mean "assist other police agency"?

Yes it can, and in this case it does. My apologies. In speaking with the Police Department they stated that they have numerous AOPA's on any given shift and it can be at any level of urgency, including extremely minor. The next step remains the same. Please contact the police department with whatever identifying information you have for the AOPA that you are interested in and they will be able to research the issue.
