These guys were caught by an HOA board member checking out the pool's $15,000 water heater. Not in the clip but they were confronted in the parking lot minutes after they exited the gate.
They may have been looking for a place to take a dip later that night and were trying to figure out how to turn the heater on so the pool was heated up when they returned. Maybe they were planning a late not party at the pool? I wouldn't think that they would be trying to steal the heater, but I have not seen it all yet.
I bet these guys have stolen copper coils out of air conditioners before.
