The cops advised me I shouldn't be walking in the bike lane that everyone walked in because there was no sidewalk on that side of the road. Having advised me of this, had they stopped me again, they would have ticketed me. I then had to routinely expend extra energy to go out of my way going "home" every single day.
No, the cops absolutely weren't going to help me solve any of my actual problems. No, they absolutely didn't care about me, no.
Calling the cops on a stranger because you supposedly care about their welfare is asshole behavior. I don't care at all about your supposed justification or algorithms etc.
If you care, you check on them yourself or maybe call an ambulance. If you don't know them well enough to do that without it going weird and shitty places, then mind your own damn business.
