You don't profile based on a crime.  You profile based on the suspicion of a crime.  Let's say that someone reports a burglary in their neighborhood.  The police are dispatched and on the way there they see a black guy in a hoodie.  He avoids making eye-contact with the police and they decide that that is suspicious and they want to talk to him.  After all, black people disproportionately commit crime, right? Once the black guy realizes that the cops want to "talk" to him, he runs.  After all, how often does an encounter with a police officer end well for a black man?  The police chase him down, tackle him, and handcuff him. Good for blue, they didn't shoot him.  As they search his clothing, they find a small baggy of marijuana and arrest him for possession -- and they tack on resisting arrest for good measure.
