Good parsing.
I do not object to LEOs, but LEOs ought to have the same authority as ordinary citizens and the reverse ought to be true. I am not one for special classes of citizens.
You are incorrect about how any gun owner has as much ability to harm me. LEOs have a much greater ability to harm any random citizen. I could go into details, but do I really need to? This one is pretty obvious.
This is likely correct. The gravity of harm, however, must be taken into account. My favorite excoriated former SecDef posited a sort of mathematical formula that consisted of probability * gravity to rate a threat.
Do you know what a Risk Assessment Matrix is? I'll show you.
You mentioned the probability * gravity, and you're right. What you have with a police raid going wrong is a situation that is catastrophic in terms of severity, yet very very low in terms of probability. With other risks, like the aforementioned getting scammed by an auto-mechanic, the severity could range from negligible to critical (next time a young couple trying to make ends meet is told they need to sink $2000+ into a new transmission when they don't really need to, tell them it's not a big deal). And yet the probability of you or any one of us getting overcharged or even royally screwed by a mechanic in our lives is Likely-Frequent.
A big deal is made about a few highly publicized police events that happen to fit the emotional agenda of some posters. I would wager nearly every single one of you will never experience such an event in your entire life. But like I said, over-hyping these events fits with an overall anti-authority theme, so you let it slide. Yet other times people in other professions screw you over, and frequently, it's ignored because there is no big deal to be made about a grease monkey charging $478 for a $35 part and 20 minutes of work.
It's just plain that some people have an agenda, and either go out in search of stories about these highly infrequent events to back up that agenda, or allow themselves to be hyped by the media because it strengthens their emotional attachment to said agenda. To be blunt, it's really no different than an anti combing a stack of news stories about gun owners for the handful that legitimately show a gun owner who acted recklessly, and totally disregarding the pile of incidents when gun owners act correctly. They only allow themselves to see things that fit the conclusion they have already made.
