Here's how the cycle works. We decide a certain group of people ("literally the dregs [sic] of society") causes most of our problems. Then we pass laws targeting that group, and enforce the laws most strictly against against that group — and surprise, that group ends up getting caught breaking the law most often! Then we use that to drum up further public sentiment against that group. Rinse, repeat.
Crime is a social construct. We choose what's illegal and what's not. We enforce some of the laws, against some of the people, some of the time. Saying that a certain group commits the vast majority of crimes is meaningless without additional context. And if your additional context is that they're "literally the dregs of society", you're not being serious — you just have an axe to grind.
