It seems overall trust in the government have increased slightly. All these people who were caught up in the moment and were suspecting that government was trying to cover something up saw instead the government was actually trying to protect the privacy of the family.
Now you force the government to reveal the security footage and we see the last few minutes of this young man's life. After this some people have done some soul searching and realised they didn't actually care if someone ate one bowl of rice jelly or two, but were just crowding around watching him slice open his stomach. Well now you have your answer but he's dead.
It's also woken up a lot of people on just how closely foreign agents might be operating around them and the dangers of coloured revolution. The people's level of alertness regrading security have also increased.
Yup, one should always "let the bullets fly" their full course.
Any commentary before that is just attempts at fortune telling.
