This doesn't seem better?

I'm an employer and I want to make sure you haven't committed any serious crimes, so I ask for a certificate saying you haven't committed violent crimes. I get a certificate saying you have. It was a fistfight from a couple of decades ago when you were 20, but I don't know if it's that or if you tortured someone to death. Gotta take a pass on hiring you, sorry.

Seems like the people this benefits relative to a system in which a company can find out the specific charges you were convicted of would be the people who have committed the most heinous crimes in a given category.
