Maybe I missed it in that article, but the Texas Legislature just passed a bill that will make it mandatory that every public school in Texas has an armed security office on campus. It's just waiting for the governor to sign it. I didn't read the entire bill, so I wonder if the armed security office mandate means someone meeting those qualifications must be on the same campus all day, or if they are allowed to make rounds between other schools? It's common for School Resource Officers to make the rounds to a few campuses during the day.
