-isn’t the “armed citizen” actually an off duty cop in addition to what you stated?
I don't have any firsthand knowledge, but the pastor of the church stated she is a volunteer, a member of the congregation, and when asked if she is a police officer, he stated she has law enforcement background. So, technically, I consider her a citizen rather than a hired security guard.
Regardless of her title, she is a hero and saved a lot of lives yesterday.
