Teachers in places where the scheme has already been piloted have received training from private security firms. In Harrold county, teachers have also been provided with special ammunition that avoids ricocheting and therefore minimises the threat of students being caught in crossfire. [1] Other schools in more urban parts of states like Texas, particularly those suffering a high level of gang violence, already have their own police forces. Many American schools are therefore used to having an environment where arms usage is the norm. It is therefore hard to argue that introducing armed protection in a different form, aka through teachers rather than police officers, would result in an increased level of risk.
