Illegal activities are taking place, I would say this as for example you don’t know if the person is dangerous or is armed and you could be arrested as you may look like you are involved in it
A passive-aggressive comment can insulting or the person may be wanting to manipulate another. This can also frustrate someone because they would like to get to the point of the problem, while a passive-aggressive person would not. I ultimately feel as if it’s different for every person. In general passive aggressive people like to manipulate and never give direct requests.
