So, not all cops are dirty but that exists because they're humans. There's a 100% chance we'll run into dirty cop social workers acting like thugs and using those armed guards as leverage or intimidation factor. 100% chance mistakes will be made as well. Just like now. Society will associate these social workers they same way they do police, over time. Some hate cops and will hate those social workers in the exact same way. Look at mall cops. They're cops, but they're not cops. Does society respect them because they're cops but not cops? Watch how any shoplifter will gladly lie, fight or run from those security types, not giving a crap who they are or how they feel about anything. But as soon as the cops show up in most cases they're calmly walking away in handcuffs.
Have a look at this routine traffic stop. Think about how each and every encounter with another human can end like that and think about how there's nothing one can do to prepare, other than be as prepared as possible, for anything.
Why would anyone want to place an unarmed talking piece between two potential guns both pointing in the direction of the words?
