It’s their job. They are supposedly trained professionals, but they were just cowards. They would have stood a much better chance than unarmed children in the school, especially four of them working together. They should all be sacked and their pensions revoked for being pathetic wasters of space. They wouldn’t even go in when back-up arrived.
Time to arm pupils as well. Why would you send your kid to school unarmed knowing that the police won’t protect them?
