I like it when people do their do diligence.. and crime/safety is certainly part of that. I've attached a map that shows crime stats in 85020. It may help you. We often have our clients call the Phoenix Police department and talk to a neighborhood specialist.
If you would like to take a little tour of 85020, I'd be happy to drive you around the neighborhood... since my office in in 85020, I do know the area very well.
Hope this has been helpful... Gene
