The recent headlines about flash mobs are causing many to wonder, what do you do if you find yourself in a flash mob? Frank Farley, a professor in Temple's College of Education, says people need to remember that we're in a post-9/11 world. He advises — take out the ear buds, stop texting and pay attention: "If you are not paying attention to your surroundings, you may be caught right in the middle.  Very good advice is to stay in touch with where you are and what you’re doing."
