A medical determination is not sufficient to make something a crime.
Completely ignoring the first part of the quoted text, which is that they
violated procedure during the arrest.
Proximate cause... the man's obesity and medical conditions caused his death.
If someone has severe arachnophobia and you put them in a confined space with tarantulas and they have a heart attack and die, what caused their death? YOU PUTTING THEM IN A SITUATION WHICH TRIGGERED LATENT HEALTH ISSUES.
If someone is allergic to peanuts and you drop a peanut in their coke and they die, what caused their death? YOU PUTTING THEM IN A SITUATION WHICH TRIGGERED LATENT HEALTH ISSUES.
This is Logic 101. And Law 101. If you aggravate a condition that would otherwise not have been aggravated without your actions, it is your actions -- not the latent condition -- that is the proximate cause.
I'll ask you the same thing I asked NJNP. Why do you think you know better than the grand jury? Reviewing the facts and evidence has been their full time job for hours upon hours and they reached this decision based on more information than any of us have.
Oh, I don't know more than the grand jury. In fact... if you scroll back in this thread, I made a similar comment to NJNP about Ferguson when the news broke... so this is a bit ironic. But, I do have eyeballs. And I can read police guidelines. There may be reasonable doubt to whether the cops are guilty of a crime, but there is no way that you can watch that video and read the text of what cops are NOT to do and think there wasn't probable cause for arrest.
And what's funny is that you have NO IDEA what evidence was presented to the grand jury or if they "got it right" because the proceedings haven't been unsealed. So, for example, if the grand jury was not provided instruction/evidence that the cop
violated procedure in using a choke hold then there was no way for them to find "probable cause for arrest." In short, it's ignorant -- in this case -- to say the grand jury knew more or acted correctly because you don't have access to the proceedings.
