Please be careful about blaming bystanders for not Doing anything…just in general. I politely asked a stranger on the path once to take their shopping bag off my shoes… I assumed they had done it by accident. And what it led to was a verbal altercation that lasted several minutes and got very hostile. They just didn’t like being told what to do. People who are aggressive and mentally ill can be unpredictable. Everyone around me disassociated while I was literally crying and shaking because this man was cussing me out because his property was on my body. So much more happened that I won’t bother listing here but the point is that bystanders just don’t want to go home to their families with a black eye because they tried to do something about it. In some few cases, Doing something can make a difference but it can be really dangerous if the person is aggressive
