My Manifesto: The Incoherent Ramblings of a Madman

I got pulled over by the police two days ago. The situation:

1. Object in middle of road;
2. Brake;
3. Swerve to avoid object;
4. One tyre goes over one of double lines;
5. Police car coming other way;
6. Police car puts on lights;
7. Police car does U-turn infront of 3 cars who each slam on brakes to avoid collision;
8. Police car indicates for me to pull over on a corner at the end of a straight approaching a bridge;
9. Police man, who is not wearing a safety vest, comes to car window and stands in middle of road lecturing me on road safety;
10. Police officer checks to see if I have been drinking;
11. I inform Police officer if I had been drinking I would not have been able to avoid obstacle;
12. Cars swerve to avoid police officer at last minute due to his standing position and my stopping position he forced me into;
13. Police officer is undecided as to what charges he can give me and is thinking out loud when he mentions: reckless driving; failing to indicate; crossing double lines; negligent driving;
14. Police officer has no fine book on him and vowes to return to office where he can go through the road rules to work out what he can charge me with and says fine will be in the mail.

What gives him the right to lecture me on road safety when he has endangered the lives of many, including himself, on his quest to lecture me on road safety?

The only thing I can see that I did wrong was not indicate when swerving to avoid the object, even so, at no stage did I endanger anyone elses lives. Or is there some other thing I am missing? What should I have done or should I do if it happens again?
