See, that's exactly what I was talking about. We had seen countless things that should have caused massive reaction from the public. We have seen cigarette smugglers bombed by the government, mistaken them for terrorists. We have seen nobody being charged for that. Countless cases of fraud by government officials go unpunished. A 13 year old girl getting raped by 26 men and the perpetrators get away with only a few years because they claimed "the girl didn't resist them."
Seeing these things not getting any reaction from the public made everyone depressed. But it all accumulates in people's conscience. I might be wrong about what the tipping point is going to be (in fact I probably am since these things tend to happen at very unexpected places) but there will be a point that people just can't take it anymore.
