The USA has a philosophy of having loose laws and occasional enforcement. This is partly cultural, and has a lot of negative side effects, particularly for minorites. It's pretty easy to do drugs or drive 5-10mph over the speed limit as a white person, but it's much more risky if not.

Contrast much of Europe, where speed enforcement is done by camera. I got a $20 mailed ticket for driving 5kph over the limit. Fair, easy, scales with the offence, and there's not an excuse to pull over people for racial profiling.

So yes, I would love to live in a world where people got tickets for jaywalking on an empty street. Because that would encourage us all to respect laws, and would also encourage reform of laws that aren't working.

Unfortunately, reform takes time, and there's a lot wrong with the system. Until then, I'm not judging the "regular person snitching," particularly if they're complaining about behavior that's dangerous to others.
