I had a convo about law enforcement's tools with a California detective last month. He was very clear its only a question of resources, and if the federal gov't is motivated to find them, they will.
You know I’ve generally thought it’s is true. You WILL get caught. Then I wonder if the government knows who Satoshi is. I know he didn’t kill someone but I wonder if the resources exist to figure it out if they truly wanted.
I wonder about the Jan 6 pipe bomber
"The government" is not a monolith. It is an organization staffed by people who have different opinions, motivations, goals, etc., and often work at cross purposes. It's entirely possible that some in the government know who Satoshi is and aren't telling others (especially higher-ups) about it.
Guess the government wasn't motivated enough to catch D.B. Cooper
