Castle Rock was my old stomping ground as we lived in Larkspur. The Gonzales case confirmed two things at the US Supreme Court level:
1. The police are not required to show if called.
2. The police are not required to perform heroics if they do show.
Without question, the Castle Rock v. Gonzales case confirmed those two items and that we are responsible for our own defense.
I am also familiar with Castle Rock. I used to live in Coal Creek Canyon NW of Golden and often had to drive to the Colorado Springs area for work. I am surprised that their police department was so unresponsive.
