I would hazard to say that most people are upset because a single person decided the fate of our country, and in a manner contrary to the outlines defined in the constitution. And your description of the events there really do clarify just how awful things here are as well - executions in broad daylight, masked men kidnapping people extrajudicially, allegations of laws being violated as a pretext to detail lawful citizens.

It's all horrible and shocking to say the least. And it makes people question whether our actions are justified or the outright thuggery of a wanna-be dictator.
