I hear you. I'm afraid our countries shared the same social maladies.
Police (all branches of military uniforms) abuse and corruption is.one of the worst problemas we have in Venezuela.
The current regime has made sure that no one wearing a uniforme will ever be free of guilt, lest they pay the prices. Most people in uniforme have miserable salaries. Poverty and lack of education are the first causes of their submission to corrupto and brutal powers.
Even though their families suffer the same issues like any other citizen, and even though people in uniform will need of the average citizen (teachers, doctors, streets vendors, drivers, etc.), they abuse them without any consideración.
There might be exceptions to this rule, but those who might refuse to do evil are overwhelmed by the majority and kept in the shadows.
