Whether it be giving teachers and staff weapons and proper training to defend themselves and students. Or hiring security guards and upgraded systems in every school.
Whatever it takes to keep the schools safe. There are many ways to prevent these attacks. Parents send their kids to school where they are supposed to be safe, but after todays events that is no longer true.
Parents should rest easy knowing that their child is safe at school. But now no one can be sure. The next maniac could strike at any moment. So why risk another attack when we can prevent it from ever happening again.
Even being more cautious when letting visitors into a school can make a difference.
