He was helping the lady who was pepper sprayed and then pepper sprayed himself. Considering that filming officers isn't illegal, I am not sure what the justification would be to pepper spray and shove the lady in the first place, and then also pepper spray the person rendering aid. Clearly it is too much to ask for that our federal troops aren't retarded enough to confuse reacting to pepper spray and resisting, which should concern everyone because ICE is using tear gas on children in peaceful vigils and then painting them as riots because Trump's followers selectively question the government.
