Yes, although someone else here pointed out to me that the Speaker actually did say he wanted faces blurred to protect those folks from DOJ, which is absurd 1) because I agree that those clowns need to face consequences, and 2) it makes no sense given that DOJ already has the raw footage.
Still, I'd hate to encourage reddit-style vigilantes even if that seems at odds with the fact that the FBI posts images explicitly looking for help in identifying certain suspects.
Well, no, I don't think that's obstruction. He's not hiding them from DOJ, since they already have the footage. Choosing to not publicize faces for John Q Public won't get in the way of their prosecutions.
FBI has their list of most wanted including pictures.
So this is perhaps not helpful at worst, and avoiding vigilante justice at best, is what I'm thinking.
