They didn't need to escape though. According to Tesla at least they were asked to stay put for police to arrive. Sounds like they wanted to get out of there and not get into trouble.
Of course I am not justifying the actions of the journalists, but this is most certainly provocative behavior on part of the Tesla employees. If someone breaks into my home, I'd absolutely let them run. I'm not gonna say "Stop! Let's wait for the police" since for all I know they could be carrying a weapon. It also seems they were blocking the SUV with their ATV. I'd have gotten out of their way once they made the intention to flee the scene clear.
