Professor Hobo – college, students, professors, & cats

To the best of my understanding we have technology that can block cell phones in movie theaters.  Why are we not using it?  Why not just install it into every theater in the country?  By law?

I’ve heard the arguments against such tech.  Perhaps someone really needs to be available?  Honestly, if you’re so important you can’t be out of touch for two hours, you probably don’t need to be going to a movie in the first place.  Sorry, Mr. Obama.
