Consider Sral, the moisture farmer.Why would he support the Empire?
Maybe that the old republic and it's bureaucracy may have been more opressive? e.g.
- For years the Sral family was strugging to get support for a law that would regulate water prices on Tatooine and over the last few generations the Srals have been struggling harder and harder and the republic bureaucracy did case study after case study.
Now the Empire has come along and fixed water prices and the Sral faimly is in the black for the first time in generations.
Sure, the Lars family were killed and burned out of their home but they were harboring and aiding a known criminal (Ben Knobie) and their son became the leader of some leftist military orgnization.
Could it be that the common day to day life of the average citizen has changed very little or not at all with the Empire? Palpatine wants control of the galaxy and if he can control the galaxy by not interfearing with the pathetic misrible lives of the common citizen? So much the better.
This consideration sets the stage for the political mindset of the common citizen.
The people in Power
Also I really don't think you would see the atypical Central American Dictator type (or they would not last very long). That stereotype misses one thing. The Opressive Dictator Ruling over top of them and other Regional Governors ready to take over with the the possible help of Papaltine. The atypical Central American Dictator type Regional Governors would be replaced by the Grand Moff Tarkins very soon.
How would a Moff, who can survive this political atmosphere, react to an abuse of power by his subordinates that drew the attention of the public? I think the Imperial Investigation into an incident like this would go along the lines of
A: Did it futher my goals?
B: Did it hinder my goals?
C: Did it futher the goals of the Empire?
D: Did it hinder the goals of the Empire?
E: Can I get blamed?
This is not a political system where you want to provide anything that could be used against you. Someone who blantly disregards Imperial law, regardless of their position, would be providing ammunitation for their rivals.
