I thought that, too, about anyone wearing purple. I hope that their houses or something are marked; not just clothing. And the chain of command is an excellent idea, too! I hate our world has gotten to this point. I used to walk home from school. There are so many sickos out there now, I would let my dog walk alone, much less my child or grandchild. Gone are the days of letting your kids play outside and get exercise and sunshine; walk home from school and share chit chat and secrets with their friends; and feel safe and protected by the world.
