I feel like the underlined reasons above are especially relevant to finding behavior observably "suspicious". The reason is, we have ALL been in situations where we were about to do something, typically in a public place, or "vulnerable" setting, where we made efforts to conceal our actions, or to reassure ourselves that our actions would not be seen/noticed by others. Let's say you're in your car, in traffic, parked at a red light, and you've got a giant booger up your nose that is annoying the hell out of you. Some people will just go digging with total disregard for anyone who may witness this socially-repugnant action, while others will give a few cautious looks around first, to make sure the "coast is clear" before they do such a deed. The same goes with farting in public.To clarify, my earlier question was about people looking suspicious based on how they carried themselves, dressed, looked around, etc... their general demeanor and posture.
As we are humans ourselves, we all have an intimate understanding of the observational faculties possessed by other humans with which to observe our actions; particularly sight and sound (and occasionally smell, in the instance of public flatulence, or hiding that dead body underneath your bed). With that understanding, we can empathize with the intentions behind the observed behavior/actions of others, without them actually telling us why they are doing what they are doing. This ties directly into finding observed behavior "suspicious", because we can empathize WHY a person might be scanning the area to see if anybody can see what they are doing, or if someone appears to be taking specific measures to conceal the sounds they would be making. Therefore, I say that one can absolutely identify "suspicious" behavior in others, through observations, merely because we can empathize with their actions from our own similar (if not also criminal in nature) experiences.
