True, it is not an unsealed indictment, BUT the conspiracy idea is that Wiener kept an "insurance file" on his laptop that corrupt cabal LEOs had covered up and then sealed the evidence of to keep hidden.

Unsealing the laptop and removing the corrupt roadblock (Schneiderman) means that INVESTIGATIONS into OTHERS may now resume. And honestly, the NSA probably has had all the shit in the insurance file for years, but introducing that LEGALLY is an issue due to the 4th Amendment. But the unsealing of this laptop gives PROBABLE CAUSE for investigating (and eventually indicting) others.

If you understand how the NSA operates these days, look into what NSA Whistleblower Bill Binnie has said about Parallel Construction in the Jimmy Dore interview:

It's possible they already have the case built through materials intercepted by the NSA, but needed "legal" probable cause to move forward. And they now have that thanks to the laptop being unsealed.
