It’s not obstruction to blow a whistle and take pictures of the ICE agents, but it appears 5 of them broke his ribs just for that.

The purpose of the whistle is to alert potential targets to the presence of ICE agents. If that's not obstruction, what is?

The purpose of the photographing of ICE agents is to identify them for later assaults upon them and their families. Do you find that acceptable?

Do your questions require common sense or can I just hazard a guess?
