Yes. Fortunately, most of them, who get adequate counseling, reveal a true willingness to change, and feel much remorse about what they have done. There are even programs where the victims confront the perpetrators. You can tell which ones have no conscience by the way the face their victims. They probably stole the car to use for the drive by shooting, because that makes it impossible for the police to figure out who did it. It was a gang initiation. The chances of that happening to you again is near zero.
I am shocked and appalled the police did not explain this to you and ease your mind. They are negligent. I hope you let them know that.
