A. It is unlawful for any person to intentionally prevent or attempt to prevent a peace officer, acting under color of his official authority, from effecting an arrest of the actor or another by:

1. Using or threatening to use physical force or violence against the peace officer or another;

2. Using any other means which creates a substantial risk of causing physical injury to the peace officer or another.

B. It is no defense to prosecution under subsection A of this section that the peace officer was attempting to make an arrest which in fact was unlawful, if he was acting under color of his official authority and if in attempting to make the arrest, he was not resorting to unreasonable or excessive force giving rise to the right of self-defense.

C. A peace officer acts under color of his official authority when, in the regular course of his assigned duties, he is called upon to make, and does make a judgment in good faith based upon surrounding facts and circumstances that an arrest should be made by him.
