I found the stats. In 2007 there were 60,851 assaults on Police Officers. Using your number of 850,000 Police Officers that works out to 1 in every 14 Officers were assaulted in 2007. Hmmmm, maybe that explains why Officers escalate force when dealing with unknown subjects who are not compliant.
Now lets move on to some of your immoral or idiotic statements.
I find it not only idotic but immoral to suggest that if a Police Officer is injured in the line of duty it is less of an injury because he has health insurance. Come on, just admit that this is truley just your hatred for the Police and has nothing to do with facts.
I have nothing but respect for the military and would never question or deminish their service so I will not even think of addressing this portion of your argument. Just imagine if I was like you and pulled only certain numbers out and then used them for my argument.
You keep going to freedom. With freedom comes responsibilty. If you conduct yourself appropriately in a free society you have absolutely nothing to fear from Police. The only time you need to fear the Police in a free society is when you exceed those freedoms.
Did you know that even just touching a police officer can land you in jail for assault? In fact, many police watchdog organizations (that usually have no problem toeing the line) specifically advise to never under any circumstance touch a police officer for this reason.
Clearly the threshold for "assault" is quite different for a police officer than it is for John Q. Citizen. Funny how the police operate like that. It's also worth noting that a lot of these escalations were driven by the police officer. Take this video incident, or the one in Utah just like it, or the thousands of others that happen without recourse to people who are poor or ignorant of their rights. It's not hard to see how police can be "assaulted" without any injury.
So I would suggest you take your figure on assault with a very large grain of salt.
What it still comes down to, like it or not, is that being a police officer is not very dangerous relative to many other professions. It's inherent dangers are exaggerated and used an excuse for escalation of force.
About the subject of freedom; The police do far more to enforce laws that simply limit freedom than to protect anyone's freedom. Tell me how that police officer that electrocuted that woman was protecting anyone's freedom... please tell me how revenue driven traffic enforcement protects anyone's freedom. Tell me how the drug war protects anyone's freedom. Tell me how coerced warrant-less searches for "illegal modifications" of vehicles protects anyone's freedom. Consider that in order to have freedom, you actually have to be free and not preemptively punished for crimes that have not been committed.
We have everything to fear from the police, they are the preferred tool of tyrants. The longer leash they are given the more they will take.
