You see a man acting distressed and carrying a gun. You call 911. What happens?
Nothing, in the case of Colorado Springs on Saturday. A neighbor of the shooter, who killed three people, saw him standing outside, with a rifle, looking "distraught" and "rough". She called 911.
However, there was no sirens-and-lights police response, because Colorado is an open-carry state.

Bettis hung up. Sadly, she had to call back a few minutes later when the shooter opened fire on a cyclist right outside her door.
that’s when I said, ‘That guy I just called you about, he just shot somebody,’”
