O had something similar to OP's experience at the LAX RCC. Laptop plugged in and turned on, sitting on one of desks. I leave for a minute to get snacks and a beverage, and come back to someone sitting their making a phone call.
Simple solution: don't put yourself in this position again. Could have been one of the staff directed to 'clear up'. Things happen. You were lucky they weren't stolen or damaged. Moving feels like a violation...but it is the least bad thing that could have happened if you were going to neglect your precious belongings. Safe travels.
Yep, it is always the victims fault and never the violators fault.
