I can't blame anyone for being afraid to go to a movie, have you seen the prices lately? 
Geeze, I am really behind the times here. The only people I know of that carry an alert device are Fireman when off duty. Could be off duty Policemen and woman in the big city's also carry them now a days, but I know of no civilians carrying them, and what need unless they may be paid TV or paper news reporters to have them.
This Nads AKA Louis Lane is giving me the idea someone in fire or police department gave her a devise that is paid for by the tax payers for the exclusive use of police and fire departments.
From her reporting as a citizen reporter that covers forest fires and occasional town meetings. she may have gone to Radio Shack and bought a scanner, but if so why ????? She does not report on police actions, fires in the city, I also have a scanner but do not take it to the movies with me. Miss Louis Lane better be carefull what she writes as someone in her neck of the woods may want to know where, how and when she received these alert devices she carries at all times.
