Allowing someone not certified to do the work is a pretty big no-no for a regulated profession. It's bad enough if a contractor allows their untrained buddy to work on your sink, but this is about criminal investigations, someone's liberty at stake. Not only would any investigation that uncertified deputy was involved in be thrown out of court, but the sheriff rightly was looking at possible decertification himself, hence why this was all public. Certification is necessary for a reason and the stakes don't get much higher than criminal investigations. The state takes it quite seriously.

Edit: And if he's this sloppy about serious matters like this, where else is he sloppy? What else is he allowing? Just a horrid look for a sheriff.

Nah bro... this is a WILD take. He allowed an untrained deputy to be involved in investigating sexual assaults against children. CHILDREN. This isn't like they put a dude on traffic duty who missed that day of training. That guy should never have authority again.

And yeah, of course the incoming guy sounds like a dick too, he's also a cop. In this case, I'd argue he was trying to do the right thing by the community though. The outgoing guy clearly should not be in charge of a Wendy's, let alone a police department.

But yeah... the Arizona thing. It's not right. We need cops who are our neighbors and community members. People that have actual stake in the community they swear to protect. Instead we have a system that rewards bad cops with cushy jobs in rural areas when they fuck up where they are originally from.
