I think that cops should stay off social media, or at least reduce their presence to a listen-only mode. There are plenty of jokers around, the cops don't need to find ways to entertain people. Police departments from all states must refocus their time, efforts, and resources in helping people who actually need their help. Witty remarks are not going to save the day. If they insist on being on social media, then let them also publish their monthly stats with case closing rates.
