I am waiting for someone to call for stone control:
"If only those stone pavers had been secured, it would have saved my son's life. We can't keep stone pavers just lying around for some little kids to access. They might stone each other.
Stone pavers need to be secured when not in use or disassembled. We don't give lawn darts to little kids (anymore), why would we let them access stones!"
"If this man had been wearing a helmet and a life preserver, he would still be alive today!"
