A harsh generalization and we should care if we're sharing the road with them. No one deserves to be dealt with violently because it serves no purpose other than to justify violence against the attacker, so while he may not want to retaliate at some point, some who watched the news and already have negative views about cyclists might be more likely to harrass a cyclist when they see one because they'll now assume that some cyclists want a bit of aggro. I don't think taking CM away will help the cyclists cause, but having cyclists take the law into their own hands doesn't help either.
