[Michlib-l] Policies for Town Lockdown

Hello library world! Our tiny town had a low-level lockdown yesterday for an escaped suspect on foot, for about 1.5 hours. Library had not yet opened up for the day so I didn't have to worry about it- but the Emergency Alert system told everyone to stay inside and lock all doors. I would really like to have a policy in place for when this happens again (hopefully not for another several decades) Does anyone out there have a current policy for such events? Could you please forward them my way? TIA Mary Gallup Director Clinton Township Public Library 100 Brown St. Clinton MI 49236
