The gunman ordered children out of the sanctuary before opening fire, killing three people and wounding at least five others in the middle of a worship service. He held 25 to 50 people hostage before finally surrendering...The gunman surrendered to authorities after about 10 minutes of negotiation.
Looks like the coward wanted to live. So if men showing up with guns caused him to stop, what principle can we extrapolate?
The thing about guns in Missouri churches is:
[A] person is prohibited from bringing a concealed weapon on to the premises of a church or place of religious worship, unless the person has obtained the consent of the pastor, priest, or person or persons representing the religious organization that exercises control over the place of religious worship.
Looks like nobody got "permission".
