So, "the presumption of innocence" is always adjacent to "the accusation". Both must be evaluated because when one appears, the other is automatically created in opposition. Both sides must be argued, regardless of your opinion of those people involved.
Once security people get into Musk's price range, they tend to handle things professionally and as a team. I am not saying they are sweet and law-abiding people; I am saying they know the laws and they protect themselves legally before starting a conflict. They start conflicts intentionally to push people away from their clients, but first they gather evidence to protect themselves.
In this situation, both parties are guilty here of pushing legal boundaries; this is about anti-stalker and anti-paparazzi laws. These laws that protect individuals and celebrities; do you think these laws only apply to people you like or identify with? There are two cases here... guy threatening Musk and Musk's people threatening the guy.
The guy was following Musk or Musk's security teams and they took video evidence of it. Once they had enough video of him following them, they questioned him in his car, asking specific questions for future court evidence, then they set up the conflict that resulted in the guy on the hood of the car and he was probably acting very emotionally.
Musk's security team will press charges against the guy and the guy is going to lose in court, because they already gathered the evidence showing he was stalking Musk, "stalking" according to the law.
Unless the guy also has evidence of that final conflict showing the security team broke the law, Musk's team will probably not be charged because the narrative in court will not be "guy was attacked by security team" but "the security team was protecting Musk and his family and the final conflict was the result of the defendant's emotional state".
Outside of this case, here is the maxim:
People who try to start a conflict with you have already have won the fight in their mind.
Maybe they have several friends with them when you are alone, maybe they are just much bigger than you, maybe they are recording video or audio and they plan to get you to say something specific, but they always believe the confrontation will work out for them and not for you. So they attack you verbally intending to escalate to violence that they can win.
So, when someone confronts you and you verbally push them away instead of escalating, like that guy who was in his car being questioned by Musk's security team, you can be certain they will come for you again and in circumstances less favorable for you. If their intent was to express violence before, they will try again. You should immediately prepare for that upcoming event. That guy who intended to continue following Musk, should have had a device ready to start recording at the press of a button before that last conflict started, so his story could be "felt threatened by those guys earlier, started recording when they approached me again, and here is the stuff they did".
