In the high crime neighborhoods that I used to work in, I would always spot people dealing drugs, shoplifiting & stealing, fighting, etc. So, I would call the cops.
Occasionally I would ask other why they don’t report these thing & why they turned away instead. It seems the attitude was always “Well, it’s none of my business”….but when something bad happened to these same people, they would blame all the whole community for not stepping in. It was so hypocritical.
I learned through observation, that having an attitude of “I’m just going to mind my own business” can ‘allow’ a community to become very corrupt.
