I hope they charge you for the repair to the cable system. What gives you the right to cut someone elses cable, compromising the system and causing other users distress. Your behavior is criminal at worst, and unethical at best. I hope this tendency toward unethical behavior prevents you from getting a degree, or getting a job where your decisions may affect the health and safety of other people. A pox on all your houses!
Don't they cane people in Singapore for this kind of stuff?
