Another deadly tornado yesterday in Oklahoma has some in Lubbock wondering why the city doesn't have tornado sirens. It seems like every year after a tornado strikes in Texas or anywhere else, I get emails from listeners who would like to have tornado sirens throughout Lubbock. Some argue that sirens would help alert citizens while critics of sirens say that people ignore them and they are unreliable. What do you think? Should Lubbock have tornado sirens?
