Church Security Plan
I believe first check for those faithful who are dedicated and committed to regular attendance. Then check for any and all law enforcement/public safety members of your church, then involved the ushers;have them be first to summon for the police,fire on the onset of trouble. That will give you some nucleus of a security minded group. We have had that problem also. They hired rent-a- cop security to be the eyes-and-ears; given them walkie-talkies, (no arms),they also installed a monitoring security 24-7 video camera system, that covers the entire parking lot and inside the church.
Peace be with You!
