They also had all those guys on camera doing crimes in Washington DC and bragging about it on Twitter.

J6 is not a strong counterexample, IMHO. Part of the problem with Epstein is "proof beyond a reasonable doubt," for which evidence is needed--and, it appears, hard to come by. Whereas with J6, there were thousands of hours of footage showing the crimes being committed (and in many cases bragged about), which made prosecutions much easier.

>With J6, in the matter of 2 or so years the FBI has secured over 1000 convictions.

Again, large numbers, but no context. How many people did you think were at the riots? 10k? 50k?

Moreover, Jan 6th was an event that definitely happened. The same can't be said for whatever happened at Epstein's island. The island exists, Epstein's a convicted sex offender, and people flew there, but associating with sex offenders isn't a crime, no matter how despicable it might seem.
