They had hard evidence of the Epstein classes crimes for DECADES.
At this point it should be self evident that the global intelligence community — likely including the agencies responsible for CSAM — are corrupt to their core and all compromised by the Epstein class of lawless billionaire psychopaths. It's highly likely Epstein and Trump's entire pedo sex trafficking ring was created by American/Israeli intelligence orgs to extort and blackmail globally, considering Ghislaine Maxwells dad was so high up that every living Israeli PM attended his funeral; some giving speeches alluding to his espionage.
Just like the police, these secret police exist to protect and defend capital. Capital IS "national security". They don't give a shit about laws, morality, democracy, or any of the other virtue signals Hollywood et al perpetuate. If they did, they wouldn't have ignored the evidence about hundreds of billionaire pedophiles, for DECADES.
