“...just pointing out that it’s not true that the cop is always believed.”
Its important that people remember that the jury of 12 are the defendants peers, and not the cops. Their backgrounds carry into how they determine which story to agree with.
I know physicians who have complained that because of TV medical/hospital shows (okay, not "Scrubs" but the other ones) patients and their families are upset when something isn't cured in 60 minutes with time out for ads.
I have a little volunteer security gig. One day I decided to explain to my boss that by asking me to do this, he was endorsing the possibility that I might kill or permanently disable someone, and that he needed to be clear about that if he wanted "Security" for this job.
I want to point out that this guy is intelligent, learned, and a good guy. I not only like him, I admire him.
BUT, that being said, he asked me if I couldn't just, y'know, shoot the baddies in the leg or something. In a jocular way I explained that even if I was aiming for the COM, I'd probably hit him in the leg, but, seriously now, when the SHTF sometimes I don't shoot as well as Roy Rogers did, what with the adrenaline and all and the possible need to check for/deal with other bogies.
He thought a minute and realized he was being a little romantic with his expectations, and then said, "Okay. Your job is to protect X, and if you end up killing someone who is threatening to harm her, okay."
I think a lot of jurors have no clue about what life is like when the SHTF, and don't know how much information has to be processed and how many decisions need to be made in a cloud of adrenaline and not very much time.
