1. Was aware of his relevant actions
2. Was aware the actions are likely to have the relevant effect
3. Acted anyway
and - again, in some legal systems - this creates a presumption of intent. The onus is then on the accused to establish that they had an entirely different intent (in which case they acted "recklessly") or was not actually aware of the consequences (in which case they acted "negligently" because they should have been aware).
I am not a (US) lawyer, so I'm not sure that's the exact legal situation for Trump.
In this example, it's probably open-and-shut 2nd degree but the prosecution now has to prove that you premeditated this if they want to go for 1st degree (IANAL). They don't get to just say "it was clearly premeditated" and then put the onus of proof on the defendant.
you can't have direct evidence of someones alertness or state of mind, only circumstantial.
the direct evidence from witness testimony is only needed if the shooting is disputed.
assuming the shooting is proven, with no evidence of intent, you can't have murder 1, and likely can't have murder 2 either and are probably stuck with involuntary manslaughter.
obviously it depends on the state.
however even manslaughter requires some requisite knowledge and intention of what you are doing - but proving something like insanity or incapacity is usually on the defense to prove.
Can you refer to an explanation of this? Or to some case law explaining the non-attribution of volition?
in CA second degree murder is the unlawful killing of a human being that is done without deliberation and premeditation, but with malice aforethought (or with an intent to commit an act)
if there is literally zero evidence available as to intent, it cant be murder.
* Intent to kill or harm someone - murder
* Intent to pull the trigger, but not to kill or hurt anyone - manslaughter
* No intent to pull the trigger (eg accidental discharge - maybe the trigger pull on the gun is very light and you put a little too much pressure on it) - possibly manslaughter on recklessness grounds if you knew there were people around or the person was there, but also maybe a lower crime (or not a crime at all) if you were being careful with the gun and got unlucky about where it was pointing when it discharged
* Not mentally competent to understand that you might be hurting someone or that hurting someone is wrong - not guilty because of insanity
* Intent to kill the person in self-defense and the person is intending to kill or harm you - not guilty of any crime due to self defense (a murder, but not a crime)
* Intent to kill someone else who is attacking you in self-defense, but you missed - also self defense (intent follows the bullet)
There are probably 10+ more other major scenarios to cover here with different outcomes. This is partly why when someone kills someone else with a gun, the prosecution tries to hit them with murder, manslaughter, and reckless handling of a deadly weapon. They don't know which one will stick, but they can be pretty sure that a jury will find one kind of intent.
If the prosecution says "Here are all the things that indicate intent" and the defense says "I'm not going to respond to any of those, because none of them prove intent" then that's rolling some pretty loaded dice with a jury.
You must have not seen much of the 2016 election crap then. It was pretty clear that it would not have any impact on his campaign by the time she was paid in October. So much crap was said about him by then, it would have been a small side story.
All election ads and promotional activities are small side stories in the scope of the overall campaign (and his family heard all the other crap said about him too!). Fact remains that the time Trump's lawyer paid off Stormy Daniels was years after the event but weeks before an election, and Cohen has already pleaded guilty to it being a campaign finance violation. In the scope of campaign finance violations it doesn't sound like a particularly massive one and the reasons for not wanting to declare it are obvious and unlikely to be related to any sort of wider conspiracy, but it stretches credulity to imagine that the election wasn't a consideration.
(In fact, you could argue that this defence is even stronger because he is Donald Trump. He has plenty of dedicated supporters who seem to stick with him regardless of his transgressions; accusations of infidelity might be less damaging to him politically than to other politicians!)
So, the prosecutors have to somehow convince a court what his intent really was, i.e. it's less about what he did and more about why he did it.
