I think the issue with the Cart Narc is his annoying behaviour.
I think that most of the confrontations would have been easily avoided if he just approached the person and politely said "Sir/Madam, please return the shopping cart in its proper place. Leaving it around may cause problems to people trying to park their car". But no, he has to do this annoying siren sound and attach that stupid magnet on peoples' cars: that behaviour alone is enough to annoy most people.
And no, returning the cart is not some kind of "moral test": it's merely a "test" of good manners.
Officer assaults would triple if cops would approach people like that.

>Two fat coppers jump from around the corner
>"Hey there, buddy!"
>I'm fucked
>"I see you're doing drugs. Watcha shooting there, buddy?"
>I try to stand up, my body fails me
>"You know drugs are bad, right..." He starts rambling...
>"I'm doing meth" I shout as hard as I can, it comes off as a soft whisper...
>"And why do you do meth? You know drugs are bad for you! Bla bla"
>Shoot me
>"You gotta turn in! You have to come with me. That's the responsible thing..."
>I resist.
>Coworker starts cuffing me as the other one just rambles
>I stab him in the thigh
>"No buddy that's really bad! We gotta give you a sticker!"
>They rough me up and take me to the car.
>Chatty one sticks a "I assaulted a cop" industrial glue sticker on my forehead
