It's even worse than the picture implies. Alex walked away from that confrontation, and then later ICE assaulted a woman in front of Alex. Alex was helping her while she was falling over. ICE didnt like him helping her so he decided to pepper spray both of them. ICE thugs jumped Alex during this and then executed him. There was zero confrontation, just murder.
I think of the quote by Mr. Rogers during moments of tragedy: find the helpers. ICE executed the helper. There is zero ambiguity what happened here.
