There's thousands of ways for human violence to present itself. The majority of which are easily accessible. Let's address why that person might be prone to violence instead of trying to tackle the unrealistic problem of removing anything that could be used as a weapon by said crazy person.
What if he took a brick and knocked the window out of a semi and drove it trough a crowd at the time the school let out? Would they be calling for trucks to be banned?
