On a technical level this is interesting. This was a robbery, not a social justice action. So money was the motive.

The three guys came up with a new business model and started their own corporation (not registered) in their garage. They then took actions to gather funds from investors. The investors turned out to be unwilling and escalated to lethal force in an to attempt to dissuade the corporate representatives. In the ensueing negotiations representatives on each side were shot or otherwise injured. The blame here clearly rests with the investors who escalted to lethal force rather than just fund the corporation.

Had this happened in the US, and caused a new business model that was very lucrative for some existing wealthy people, any crimes that occured in the process would be ignored. However, since the three individuals who formed the new corporation were not already wealthy, they would be caught and jailed.
