I don't hear Adesanya telling people to riot either so I don't understand you saying listen to Jon and not Izzy.
Jon publicly denounced what happened. The difference is he isn't gathering hundreds of people in person and getting them emotional and riled up, giving the platform and surge for the thugs who may not be just wanting to peacefully state what they're feeling. Which in today's day doesn't need to be done in public as seen by those like Jon who have conveyed their thoughts online.
Jon is going around taking down Antifa, cleaning up broken glass and graffiti, boarding up stores, etc. in his city only because there are people using these gatherings as an excuse to do whatever they want. They only have the platform to do so because of people like Izzy and others gathering them.
Go home. Leave only the rioters outside. They'll either go home to or be dealt with.
More importantly, there is a BIG difference between being charged with murder and being convicted. Most of the officers in similar cases were not convicted. With all the pressure and attention this is getting some may think that there is no way he won't get convinced but it would not surprise me because it would not be the first time I believed the officer would be convicted.
So protest, riot, loot, whatever if he gets off. You don't do it before hand when so far the system has worked. The LA riots only occurred when the cops got off, not when they killed Rodney King.
There is not a "broken system" when someone gets fired, charged with murder, literally everybody denounces the action taken as wrong, and even the guy's wife divorces him over it. There is nothing to protest right now, and people are ruining entire cities because they simply have the platform being handed to them to do so.
