Yes you should report this- but who do you report it to?
Florida DMV. They can't do anything until he gets back to Florida. Heck, even if they revoke his license tomorrow- he is still going to drive home.
I think you also need to report this to the local authorities. I would hate to see him injure himself or someone else on his drive home.
Ethics can be a *****.
