So there are things that we see in our lives from time to time that are illegal that we might not necessarily call the cops or report for. Maybe someone jay walks. Maybe you see a mother with a baby shoplifting some baby formula (though in that case, I would just stop her and buy her the things she needed).
There are grey areas where people breaking the law really isn't hurting anything, and in some cases it's even understandable why it's happening.
Where do you draw the line to crimes that you witness? Are there some things that you don't particularly care about that others might report, like observing a drug deal? Maybe you have a story to tell about something you witnessed and let slide?
I wouldn't call the police over a jaywalker. Even if I did, it would probably take the police a while to show up, and by that time, the jaywalker would already be gone. They'd have to put out some kind of dragnet and APB about a mad jaywalker on the loose.
Although there was a time when I saw a woman carrying a baby and with another small child in tow, running across a busy street in heavy traffic. Luckily, nobody hit her, but I'm often flabbergasted by those kinds of jaywalkers. So maybe they should be reported for putting children in danger like that.
As for drug deals, that might depend on the circumstances. Let's just say that for the past few decades, I've managed to avoid places and situations where witnessing a drug deal may be likely.
For the most part, I guess I've been reasonably lucky in that I rarely have had any real cause or need to call the police, at least not for any personal reasons. If there's some kind of road hazard, I'll call it in for sure. Or if I see an accident, I've called in a few of those, although most times they've already gotten the call from someone else. I also called and reported a guy in an RV who was swerving all over the road, knocking over poles and hitting stuff along the side of the road. He was dangerous, so he had to be reported because he was creating a clear and present danger.
But I've never witnessed a robbery or a kidnapping or a shooting. I know it happens, but I've never seen anything like that firsthand.
