Um...

No, he doesn't.

Read the actual article.

He's asking them, when doing background checks, to at least discern past criminal convictions from one another based on their severity, including admitted drug use that didn't result in a criminal conviction.

This request is obviously designed to discourage recruiters from using youthful indiscretions like a speeding ticket or smoking weed at a party against applicants and classifying them all under a large blanket which labels them as having a criminal background. In other words, recruiters are obviously finding any petty thing they can in applicants' pasts to counter the federal government's attempt to bring ethnic diversity to law enforcement agencies that sorely need it.

I don't totally blame you for misunderstanding the article, however, because the right wing web site you got it from obviously uses a headline that was out of context as click bait.
