AFAIK, there are LGUs that employ jet-skis in rescue operations. And the fact that ambulance yung nag-tow sa jet-ski may mean its a part of their rescue unit.
So, nakita sa SLEX. Hindi na ba pwede magawi dun yung ambulance at jet-ski? What if papaservice yung jet-ski for maintenance?
Let's be fair naman. Unless we know the whole story, jumping to conclusions will not help anyone.
