The last two.
One was shot in his car without resistance.
This one was shot reaching for his license and registration. Now, I dunno about you, but if I'd just informed an armed police officer I have an open carry permit I wouldn't be reaching for anything unless it was at sloth speeds and in full view. But I guess it's more important to learn how to fire a weapon than to learn how to behave around armed police officers when you're carrying a weapon. Every encounter for a cop in a country where guns are freely available is a potential life and death situation, my nerves would be fried too. The gun owner might go through his entire life without drawing his weapon and thinks it's awesome being a gun-owning 'Murican! And he's never learned how to behave around people whose lives are under threat everyday. This is why civilians shouldn't have guns.
And the other was shot lying on the ground without resistance.
This one I can't explain. But I do wonder why he resisted arrest, maybe it was because he was carrying a weapon?
