I speak for myself here, but it is not that I would recommend against talking in principle. Only, in practice the system is set up for talking to be universally a bad idea.

If the system puts in place some better checks and balances for people to fight abuses (as the one in the post on top), I will gladly go back and do my civic duties to stop crime.

So, how are they supposed to investigate if nobody talks? They are supposed to fight for better checks and balances, so people can start talking again.
