* They couldn't find WMD in Iraq -- because they weren't there.
* They couldn't find bin Laden for 10 years.
* They thought Snowden was on a plane with Evo Morales -- and were wrong.
So, given these observations, I wouldn't be too surprised that one guy was able to get access. Like all big organizations, I'm sure the NSA & CIA have some amazing small groups capable to Bond-like performance.
But as a whole, they are probably a nightmare of incompetence. Therein lies the reason I'm not in favor of giving them Carte Blanche for domestic surveillance: they will fuck up on an epic scale with probability=1. It is only a matter of time until their infrastructure becomes a tool for some oppressive politician or bureaucrat. HUAAC 2.0.
Bingo.
I realize this puts me in tinfoil-hat territory, but I'm not sure this wasn't intentional. He was of greater strategic value while still "alive", both to the U.S. and to the jihadists. Moreover, he had serious health problems for the last decade, and quite possibly has been dead for years of natural causes. The rapid and secret funeral at sea also seemed odd, as well as the timing, just before the election.
I have no evidence, so I can't square that circle. But given the record of shady behavior (competent and otherwise) by the three-letter agencies, neither would it surprise me.
There was a NYT story a couple of days ago which claimed that he was a NSA-trained 'hacker', he self-described as a 'infrastructure analyst', and a long time ago as a 'wizard.'

I know people who with just 'Analyst' as their titles have tech-PM'd MS Project implementations at large telco's, and others making stupid money in finance - it's also the title extraordinary spies are given in movies.
I imagine there were people with access and knowledge inside NSA who didn't want to risk becoming whistleblowers themselves, and pointed him in the right direction or outright gave him stuff.

The Kryptos sculpture has been there for all to see for many years, and the man who designed it thought it would be decrypted in months.. Yet it still hasn't been fully decoded, including by the NSA and CIA (part of it publicly was, so we know that if they did they would probably tell us).
This tells me that they're probably very good at some things, but that we also shouldn't overestimate them (the hollywood effect).
