The prosecutor failed. Beck should have been charged with reckless endangerment, or the equivalent. He took no care to avoid shooting the woman. His shooting skills suck. Pray and spray idiots shouldn't be allowed to operate and should be punished when they shoot people when they don't have to.
Wrong. He should get a medal for fighting back.
According to your logic, the active passengers on Flight 93 should have their estates sued for "endangering" the passive passengers. After all, who is to say that the hijackers would not have had a change of heart and safely landed the plane? (I suppose the same folks who say that an armed felon really isn't planning to carjack a woman sitting in a van, after he opens the door to her van).
He took no care to avoid shooting the woman
I doubt that. Anyway, if the woman had been paying attention, she would have exited the scene before things hit the fan. She was operating a vehicle in public, on a public road. As such, she has an obligation to pay attention to her surroundings. No different if she gets hit by a police car that is running it's lights, because she is not paying attention.
His shooting skills suck
3 out of 17 puts him in "cop" territory. Also, he was wounded, so cut the guy some slack.
Pray and spray idiots shouldn't be allowed to operate and should be punished when they shoot people when they don't have to.
He wasn't an idiot, any more than the passengers on Flight 93 were "idiots". He was acting to prevent the commission of multiple forcible felonies.
The chances of a bystander getting hit in a gunfight are less than the chances of getting struck by lightning.
Whatever damages occur as a result of good guys fighting back are dwarfed by what would happen if the good guys were banned from fighting back.
