Tough to be unbiased here – I walk through that neighborhood every day during my commute, and feel that a description like that is hardly a useful constraint. Especially in the few blocks around the art school (which leads toward two other undergraduate colleges), you can&#x27;t tell which folks are professors, which are students, and which are leeching off the zillion hospitals within three blocks.<p>To some, that may mean it seems appropriate to just stop and question everyone. But, in reality, being questioned by the police appears to passers-by to be an indication of guilt, and that&#x27;s not something you want colleagues and students seeing.<p>So, again, if you see a guy matching a vague description, see if there&#x27;s another reason why you&#x27;d suspect him.<p>Have a rock-solid, specific description? Maybe that&#x27;s a different story. But I&#x27;d like to err on the side of caution and respect – there are consequences even if you don&#x27;t charge the guy.
