Students at a California college say the the campus emergency notification system didn't work right when alerts went out about a suspected gunman last month. Deaf and hard-of-hearing students at California State University, Northridge were supposed to get text messages instead of phone calls. Other students got voicemail, but the text messages were never received. However, the associate director for the school's National Center on Deafness told the student newspaper that he got, not only a text message, but an an email and video phone announcement.
