I suspect Wally's browser history is a set-up. He has picked those sites for just this reason; anyone sneaking a look at his computer is going to be carried off raving and clawing at their eyeballs. He probably automated the process years ago and has no clue what is happening behind his screen saver.
Yesterday I saw press reports that the highest NSA levels were excited ( wrong word in this context) about a plan to discredit religious extremists by publishing their un - holy/sinful browsing. Reality is ALWAYS worse.
So when the NSA staff goes blind and crazy, they see the light, become rational and effective in fighting Elbonian terrorism with as their best weapon the most useless employee from the private sector - is this depressing as that feels credible or because reality is in fact worse - NSA has no hope of ever getting a WEHBCI -Wally Elbonian Hacker Blinder Crazyness Inducer.
