Most of the super-heroes I know choose to be anonymous. In this case the officer probably did you a favor. If you had injured the guy, and he knew who you were, you could have your day in court. ...and so Mr. Warlock, why exactly did you pounce from the hood of your car onto the neck of my client...how did you determine how much force to use...are you some kind of vigilante...etc, etc, blah, blah, blah. You get my point. Of course it all could of been about the paperwork and being rude. I just think that anonymity works better for you in this instance than does fame or noteriety.
