Sue everyone. I don't care. Sue the airline, the airport, the agents, cause TSA agents subjecting a severely disabled person to this is physical torture, and now his condition has worsened because of their lack of compassion and commonsense.
This was completely unnecessary.
Mercy is when you can't even explain how you're surviving, but you are. You don't have it all figured out, but each day, God sends help right when you need it. Hallelujah.
