UNDATED (AP) - Administrators at Virginia Tech are being subjected to some second-guessing over how long it took to get out a campus-wide warning in Monday's shooting rampage.
The first killings occurred in a dorm. More than two hours later, the gunmen opened fire in a classroom building, killing 30 more people and ultimately himself.
The only alert was sent by e-mail, telling people there'd been a shooting and urging caution.
Security officials at other big schools are sympathetic. And they're also looking at ways to speed up communications in a crisis. U-C Berkeley is considering sirens or an outdoor P-A system. The University of Florida is already working with police on an auto-dialing phone system for emergencies.
And Virginia Tech itself has been working on a system to warn people via cell-phone text messaging.
