So i just did some research with a law enforcement official. There are not definitive ratios between blacks resisting arrest vs whites or any other color. This is a subjective thing, but the premise that's more important is resisting arrest is stupid no matter the race.
I've heard the immigrant job taking thing for some time now (Since high school), but I don't agree that in itself it destroys blacks ability to get jobs. Now, if you're talking lower level (day laborers, construction, etc), there is a tinge of truth to that perhaps, but i'd have to have numbers to prove that. i've taken the same diversity in the workplace training for 24 years and it's same thing. Lower levels of jobs have plenty of minority workers, men and women, POC. As you go up, the bar lessens...meaning less minorities. But the opportunities are still there. I don't believe immigrants affect higher levels of earning. (I could be wrong).
