When dealing with corruption in the court system or a failure to enforce the law by local police departments, you have to articulate yourself and all available evidence, so there is a complete elimination of political bias, cultural bias, and personal bias in the justice process.
When you align evidence of others’ actions in parallel with the laws they are violating, law enforcement and the judicial process have no choice but to execute the law. If it doesn’t, you have just produced evidence of its failure.
