For example, why isn't wage theft included in the NCVS?
Surface-level answer: because in most jurisdictions, it's not a criminal offense. Steal $100 from your employer? Go to jail. Your employer requires unpaid overtime adding up to $1,000? A slap on the wrist at best.
Yet employees are victims to billions of dollars of wage theft every year! "Sixty-eight percent of the surveyed workers experienced at least one pay-related violation in the week prior to the survey. On average the workers in the three cities lost a total of $2,634 annually due to workplace violations, out of an average income of $17,616, which translates into wage theft of fifteen percent of income." - https://en.wikipedia.org/wiki/Wage_theft . Does the NCVS list that over half of employees are victims of wage theft?
Why, it's almost as if the laws were structured against poor people in favor of business. Hmm, and ethnic minorities are overrepresented in the poor population.
What about the illegal collusion between Silicon Valley companies to suppress worker wages? https://en.wikipedia.org/wiki/High-Tech_Employee_Antitrust_L... . Were all 64,000 employees counted as victims in the NCVS? Again, no, because that was a civil suit, not a crime that the police should be involved in.
But again, why is it under civil law, not criminal? (There's no hint that this wage theft is due to racism.)
Or, were the events leading to the lead poisoning of the water of Flint, MI and its coverups a crime? If so, why isn't the population of Flint included as victims? If not, why not?
Or, in discussions related to the 'school-prison nexus', when disproportionate disciplinary actions are taken against students of color, are those students counted as victims? Why or why not?
You are correct. All this inconvenient data indeed makes people dismiss the 'simple "the police are racist"' and replace it with "the system is both racist and biased in favor of the rich".
