> I really don't see how a flash-bang grenade is justified against a person sitting in front of a computer, doing non-violent crimes.

People who pretend that nonviolent crimes are some kind of special thing always confuse and annoy me. Coups can be nonviolent, should we avoid flashbangs against a group trying to undermine a democracy? The seriousness of the crime is what should matter, not whether a threat of bodily harm was involved. Are you destroying someone’s life is what matters.

We are talking about an organization ruining people’s livelihoods. Dozens and dozens of lives wrecked. Millions stolen.

Yes, less-lethal force is very obviously justified.
