golf_bhoy He was taken to Edinburgh Royal Infirmary so unless the marshalls beat him up (MartinD may know, if he was on duty at that time) or Police Scotland did (doubt it, they're mostly shitebags) then "mental case" is more than likely.
I was marshalling this morning, but on the other side of the course (am on the 2nd hole all week, and this was on the 10th tee) - only heard about this incident when the afternoon shift came in to replace us.
