Oklahoma State University sends a campus-wide alert about a gunman near campus, but not everyone got it. The suspect shot a student in the leg then ran away. OSU says it sent an alert to 20,000 students and employees. About 1,000 of them never got the call. The University is not sure if a glitch is to blame, or if some people did not sign up for the alert.
I wonder if the person who was shot was one of those who failed to receive an alert. I must admit though that a failure rate of 5% isn't that bad.
