Before I posted my question, I thought about it. I know a simple political arrest doesn't harm the politician, it actually makes them look even better. Rather, credible proofs should be gathered and these leaders should be sent for a longer term. Every single person who are found vandalizing should face grave penalties. It's because of these leaders who provide them the safe heaven that protestors resort to merciless vandalism and terrorist (what else would you call them) activities.
