I don’t think you understand how infrequent mass shooters are. Nor how predictable lol.

Are you quoting the timeline? Is the alert ready system something unique to Canadia? Does it geofence? Who needs to approve it? How does 911 or equivalent contact them. Do they have it? Do you need supervisor approval? Is your supervisor even there or is he shitting? Half your recent 911 calls in the last 5 minutes have hung up after 20 seconds. Most of them just screaming. Can you triangulate? Do you hang up? Are your other coworkers getting calls too or did you get the only person who had their phone in class because they didn’t let their teacher take it?
