It's interesting that they would choose to blur them if it's that sensitive considering blurring things isn't actually destructive and if you were to figure out the settings they used to blur then you can easily apply the opposite effect to unblur the image. To be truly destructive they should use black boxes over faces.
And regardless of the method they use it really shouldn't take long to do either.
I don't think she's really talking to them or expecting them to suddenly admit what they are doing and change their actions. I feel like she's moreso talking to the American people. I know personally it at least gives me a modicum of hope to see that there are still people who will stand up for what's right and call them out on the floor of Congress. It's certainly better than living in a world where no one challenges them anyway.
