We’ve been sitting on a powder keg for a while. It doesn’t take many people to start some shit - a few more assassinations and things will change fast.
Things will change for the worse. We just elected Donald Trump and the government is controlled by conservatives. How exactly are you expecting them to react to CEOs getting assassinated? You think they're going to come to the table and work out a plan for universal healthcare, a compromise?
Fuck no, they're going to fight fire with fire. And they've already proved they can manufacture consent from average Americans by taking advantage of their stupidity to make them go against their best interests.
I'm sorry for your loss, but this nonsense isn't going to bring anyone back, it's just going to lead to even more suffering and violence.
