Yes, people were aware but feel they have no way to change it. Be it lying politicians, or the general problems of a two-party system.
The killing of the CEO made people feel it is possible to fight back at the system. Futile or not, at least “something”
This is what happens if citizens feel disenfranchised, which is the key here. This will scare some powerful people which it should. This is what you get in an unjust system.
I agree that that things will most likely not change, at least if we don’t take the opportunity to discuss why this happened and why people “cheer” on the killer.
Doesn’t matter, your life will be ruined either way by everyone around you that wants a piece of the pie.
Life pro tip: don’t win the jack pot. And if you do, keep it as much a secret as possible.
