By that measure then 3 people should be charged for Jan 6 I guess.

One thing has nothing to do with the other. I'm sure they charged whomever they could prove broke any laws. I am not familiar with this incident. You challenged "us" to find anyone who had been punished. It only took a few seconds for me to find one. If I bothered to dig more, I'd probably find more. But if you can't be bothered, neither can I.

Just like I really can't be bothered to look up all the people charged/convicted for Jan 6. I know several people have been convicted, and at least three Proud Boys are doing some serious jail time. Largely because those people were stupid enough to think that social media was somehow private, or inadmissible. So the authorities have LOTS of incontrovertible evidence about who was there, and what they were doing. (Pro tip: don't film yourself in the commission of a crime, nor confess to a crime -with pride!- on Facebook or some other social media outlet. Oh...and another tip...deleting a post does no good, because once you post it, it's forever.)
