Did you ever point the gun in any direction or just have it ready? Were you disarmed while talking to the police? From the way I read your post, I don't think you were which means that you've got much nicer cops than I do!Assuming you didn't start pointing the gun in the general direction, I think you did the right thing. The reason I say this is because I think it would be dangerous to point the gun at something you're unsure of. I think a 'half draw' would've been appropriate. What I mean by that is having the gun pointed at the ground half way between the target and your feet. I practice this technique often and with practice, you can be on target, ready to fire almost instantaniously (sp?)
Either way, I was worried by the title of your post but I'm glad to see everything worked out okay. Also, good thinking by calling the cops. A good rule of thumb is if you pull your gun, you call the cops!
