I'm not sure if that's a good idea to start as a trend. It'd make it easier for actual ICE agents to hide in plain sight.
I don't think making it easier for state-endorsed terrorism to fly under the radar is a good strategy for stopping it. If you physically intervene with every terrorist-fashioned individual you see you're much more effective when they're all actually ICE and not just trolls. And I'd very much recommend that course of action.
I've got a backup of it, as others should too if they've got their own git forge https://git.ngram.ca/mirrors/lapd-face-search
