What right do I have by not stepping out of my car while in my parking space and then was pulled from my car?

If you were told by the police to exit your vehicle, you should have exited your vehicle. If you did not and had to be "pulled out by the police" you can be charged with resisting arrest, obstructing a police officer, etc. I suggest that you contact an experienced criminal defense attorney for a face-to-face consultation and give him/her all of the facts surrounding your situation. He/she would then be in a better position to analyze your case and advise you of your options.

The officer apparently saw you commit the offense and followed you. He can do so. He can also ask you to step from your car, even if in your parking spot, if he has probable cause to believe that you committed a crime. From you explanation, ift sounds like the officer did have probable cause.
