It is obvious you have never worked in an investigative agency or really understand the politics involved.
First, this is a case that is being brought by the federal government. A high profile case. This means that the political stakes are very high, which can play a huge role in the prosecution of this case. So let's put things in order, shall we?
As a federal case in the Western District of New York, this falls under the prosecutorial purview of the United States Attorney's Office. Currently, that would be William Hochul and his deputies. For those unaware, the USA is an appointed post by the President. In a little over a week, this man is going to know if he has a job or not since his position is tied to Obama's success or failure. Contrary to popular opinion, many of the higher level government officials are pretty smart cookies. They know how to take an opportunity and they know how to position themselves. Having one of the highest profile civil cases taking place in your district with one of the highest profile companies on the planet is like a gift from above. Don't piss off Facebook and there might be a nice position with them either directly or indirectly through the big law firm you'll become a partner with after you leave the USA's office.
This up's the stakes. Now, the deputy in charge of the criminal prosecution division will be getting pressure from his boss to look into this Ceglia guy. After all he's a bad apple having previously been charged by Andrew Cuomo when he was the AG of NY. So the criminal prosecutor tells the Special Agent in Charge of the local FBI office in Buffalo to look into this. A case agent is assigned, along with the other bundle of cases already assigned to him or her, which could be anywhere from 10 to 40 in various stages of closure. So the case agent makes a couple calls to obtain the evidence, in this case the hard drive images and other bits and pieces, which are probably in the safe keeping of Facebook's attorneys, Ceglia's attorney's, or both. They may even do a warrant for new evidence.
All the computer evidence will get shipped off to the FBI computer lab, which in this case would be the regional computer forensics lab in Buffalo. There, a multi-agency task force works that sifts through submitted computer evidence for forensic artifacts and puts together a report on their findings. And that's exactly what they will do. The Ceglia case will get put into the queue among the cases dealing with child exploitation, terrorism, homicide, etc, and will be given a schedule for completion of somewhere around 6 - 15 months, since after all, this is just a fraud case. But with a little prompting from some highly placed prosecutors, the case will be fast tracked for completion in probably 30 days or less.
So, with the information back from the lab, the FBI agent now compiles the data, meets with the prosecutors and decides options. Do they have enough to go on? Do they need to dismiss the case? Can they bring it to the grand jury? Do they need more? Is the game plan to really bring this to trial or is it to force a plea or to simply destroy credibility?
Sometimes, in a high profile case, a perp-walk is more than enough to satisfy political goals. Ceglia was arrested and the Slashdot hivemind has already convicted him and believed 100% all the claims of the prosecution. Send him to jail now - no need for a trial or to have the evidence reviewed by a forensic examiner on the defense side. The perp-walk worked again. It's more than enough to let the USA be known as a friend of facebook in the event this election doesn't go down the way he would like.
But what about everyone else? The criminal prosecutors? They are career prosecutors so regardless of the administration, they will have a federal job until they decide to retire. The FBI agent(s)? They aren't in much danger of layoff. They will simply keep marching along until their next case comes up or until they rotate to a different duty station or have to go to HQ. The RCFL plugs along with their case load.
In the end, the only person that really has a stake outside of their federal employement is the USA, simply because his boss may or may not win the election. But, William Hochul worked for many years as a federal prosecutor doing some very high profile cases. I personally can't see him losing his integrity now over something like this, since his post political career will no doubt be very secure regardless. Is there political pressure on this case? Absolutely, the whole thing reeks of it. I have no idea where it's coming from though. Probably someone placed high enough in the administration to put pressure on a USA.
Is justice not being served while working on this case? Of course since there is a scarcity of resources. But then again, most tiny crimes won't ever get the attention of a federal prosecutor. Unless there's a news-worthy sum, it just won't. It may get the attention of a state level agency, but the feds have a price for entry.
