Actually, we have 3 kids in the school right now that have anxiety disorders. Those kids are given warning of the fire drill before time and one is taken out of the building before it happens, and even then he paces back and forth wringing his hands with worry and saying "what if it's real this time - what if it's real this time."
The Tennessee law says "reasonable fear" - someone with a mental illness doesn't fall into that category.
Then the kid’s a nut who needs to be put away for his own good.
