Two of those people were not involved in any of the planning and discussion of weapons via Signal and still got 30 year sentences, for the magazines bit. The shooter claimed he only shot because he saw the officer shooting at the back of fleeing unarmed protestors - this type of law enforcement is frowned upon in most other countries but regularly happens unopposed in the USA and officers will claim and most of the time get qualified immunity. The whole prosecution feels of a kind of the misuse of laddering and felony murder charges.
