There are two more problems:<p>1) Most importantly, responsibility and justice must be on an individual level: An individual has absolutely no responsibility for the actions of others who happen share some characteristics with them. If I&#x27;m short, I&#x27;m not responsible for what other short people do and shouldn&#x27;t suffer any consequences from it.<p>2) Profiling leads to many false-positive errors. Consider that even the disparity is so large that 1% of group A and only 0.1% of group B is criminal:<p>* If your customers are 99% group B, you will see ~10 times as many group B criminals as group A.<p>* If you suspect everyone in group A, you&#x27;ll be wrong and harassing innocent people 99% of the time.<p>The real problem, returning to my first point, is objectifying people: Seeing them as merely threats to your store - like a 2-dimensional character in an action movie - instead of real people with their own lives, feelings and interests. It&#x27;s much easier to do with people you are unfamiliar with, such as other cultures, races, economic classes, etc.
