So do nothing


Emergency notification systems that send automated text messages and voice calls to cell phones are unreliable and slow in a crisis and even could interfere with 911 communications, according to a study by a Georgia Tech scientist.

The University of Georgia and many other U.S. colleges and universities have adopted alert systems that deliver warnings through cell systems, especially after a 2007 mass shooting at Virginia Tech that left the shooter and 32 other people dead.
But even in the best of conditions, cell phone-based systems are not able to meet a federal emergency alert goal to reach 85 percent of the population within 10 minutes, according to Patrick Traynor of Georgia Tech’s Information Security Center.
