Community guidelines

This is an initial draft.  It's not complete but is far enough along that it's ready for more eyes and comments.
We are missing an area here..  We cover general threat to attendees or if our perception of safety for anyone is in doubt, but threats of future violence don't exist only in the near term.

We should adopt a policy that if there have been threats, implied or express, we involve law enforcement.  This is similar to the pattern around domestic violence.  If we offer the victim the choice, there is a strong chance that the victim, just wanting to minimize the scenario, will decline to involve the police.  Just having the call on record to a police agency can help if future incidents occur.  I personally cannot follow the rule as it stands (and I understand that there may be consequences around my job).  If there is a threat to safety made and even if everyone is safe at the moment, law enforcement needs to be notified and at least a record of the call for service and subjects contact info placed on file.
