Yes, this is one case. However, injustices happen all over the world in varying degrees. It's important to figure out the balance of damage done / good done. If one out of 100 million people is wrongly convicted each year due to these practices, but 1 out of 50 million is rightly convicted each year, then this tool net good (even though innocent people have convicted.) This is just a simple view though, it's up to society to balance this equation (but that means not having a puritist and irrationally stubborn point). What is the prevalence of accidental conviction due to the police having access to your limited private information?
