What should be done about school shootings?
After the horrible shooting in Parkland, Florida, President Trump suggested that some teachers carry guns. "We need to let people know, you come in to our schools—you're gonna be dead."
Anti-gun activists were horrified. But as John Stossel observes, many teachers have brought guns to work with them for years. Some teachers at the Keene Independent School District in Texas, for example, carry concealed weapons at school.
