Who says it has anything to do with that at this point?
The police-judicial system have a good thing going, now that real violent crime rates have overall precipitously dropped. Without pulling this sort of shit, if you'll pardon the topical expression, there would have to be layoffs in many police departments and courthouses, and that wouldn't do.
(For more on this theme, about how the police-judicial system (my words of art) need a steady diet of "the clueless", read Arrest-Proof Yourself: An Ex-Cop Reveals How Easy It Is for Anyone to Get Arrested, How Even a Single Arrest Could Ruin Your Life, and What to Do If the Police Get in Your Face (http://www.amazon.com/Arrest-Proof-Yourself-Ex-Cop-Reveals-A...)
Doing these sorts of events may be less and less practical in the future. I can think of a number of countries where people tend to build walled compounds to among other things keep the "authorities" out, or at least strongly discouraged from "visiting".
You might want to check out Arrest Proof Yourself (http://www.amazon.com/Arrest-Proof-Yourself-Ex-Cop-Reveals-A...): it presents a thesis that what I've taken to calling the police-judicial complex needs a steady diet of the "clueless" to keep all those people employed. What this topic discusses would just seem to be extending that.
For more details, including a good thesis on what drives this, an explanation for why you can have a dramatic drop in national crime rates without layoffs in what I've taken to calling the police-judicial complex, read this book, Arrest-Proof Yourself: An Ex-Cop Reveals How Easy It Is for Anyone to Get Arrested, How Even a Single Arrest Could Ruin Your Life, and What to Do If the Police Get in Your Face (http://www.amazon.com/Arrest-Proof-Yourself-Ex-Cop-Reveals-A...), and decide if you want to return to this sort of environment.
This was reified for me when I retired to the SW Missouri town I was born and raised in and an officer played a game of chicken with his vehicle and my body. From my time on the East Coast I was an experienced enough pedestrian to see that he would barely miss me and stared him down, but I'm pretty sure this was designed to get the average local to run, "crazy cop trying to kill me!", which would generate a fleeing an officer arrest statistic for him per the book.
Yes, there is that minor detail of your conscience, but then again, in a society that's so dangerously crazy, that allows the police-judicial complex so much freedom to harm so many innocents, or harmless or most-harmless "clueless" (as used in http://www.amazon.com/Arrest-Proof-Yourself-Ex-Cop-Reveals-A...), just how much duty do you owe to those who are not kin or close friends? Given the possible consequences of using my guns in defense of others, no matter how legitimately or legally, I've had to make this decision ahead of time, and it has to be that limited.
As the government gets ever more predatory, I suspect we're getting an education in why various more "primitive" societies are that way, why family, clan and tribe are so very important in them.
After edit: Another HN thread a while back recommended the book Arrest-Proof Yourself: An Ex-Cop Reveals How Easy It Is for Anyone to Get Arrested, How Even a Single Arrest Could Ruin Your Life, and What to Do If the Police Get in Your Face
which I greatly enjoyed reading and which my son is reading this week. There is a lot of good information there about how and why to stay out of trouble with the police.
I just read a very helpful book about that, Arrest-Proof Yourself: An Ex-Cop Reveals How Easy It Is for Anyone to Get Arrested, How Even a Single Arrest Could Ruin Your Life, and What to Do If the Police Get in Your Face by R. Dale Carson,
which was recommended in another thread by another HN participant. Hat tip to him. The book is very interesting and practical. (I am a lawyer and used to be a judicial clerk, but I learned new facts from the book.)
E.g. note the item on page two of the Village Voice article on "points".
