> your opinion isn't valuable.
Unlike yours, which is even though I obviously take the effort of not forming opinion before I have the information, while you seem to have formed opinion not only about the situation, but even about my motivations in discussing it, without any information to go on. If you think that makes your opinion more valuable, I think you are sadly mistaken.
Was that racist? Maybe...
Maybe not...
The thing is: We don't know.
It's easy for armchair lawyers to pass judgement... but it becomes more difficult when you actually realize that one call isn't a pattern.
By that I take it to mean that they were neighbors. So if your neighbor stops by to borrow a ladder, would you call the cops on him/her?
Imagine the case where you haven't met the neighbor before, you notice them before they knock and they look like they've been hanging around there, and it's really hard to figure out what they're trying to communicate.
Someone hearing about this might reasonably report it as "wow, calling the cops on a neighbor asking for a ladder", while you might see it as "weirdo I've never seen, who looked to be casing my place, and stammered out some BS excuse about wanting a ladder when I confronted him."
I find it hard to believe that anyone goes about their daily lives with that level of paranoia towards every new person they meet. I think it's much more likely that it's because he's black. . . especially considering the background of negative race relations and stereotypes about black people and crime.
If you've never been in a neighborhood with high crime, or where scam artists have preyed on the naive, great, but don't act judgemental toward those who may have.
