CHAPTER FIVE
Now You See Me, Now You Don’t
In April of 2013, Khairullozhon Matanov, a twentyy-twoyyear-old
former cab driver from Quincyy, Massachusetts, went to dinner with
a couple of friends—a pair of brothers, in fact. Among other topics, the
three men talked about events earlier in the dayy that occurred near the finish
line of the Boston Marathon, where someone had planted rice cookers
packed with nails and gunpowder and a timer. The resulting blasts claimed
three lives and left more than two hundred people injured. The brothers at
Matanov’s table, Tamerlan and Dzhokhar Tsarnaev, would later be
identified as the prime suspects.
Although Matanov said later that he had no prior knowledge of the
bombing, he allegedlyy left an earlyy post-bombing meeting with law
enforcement officers and promptlyy deleted the browser historyy from his
personal computer. That simple act—erasing his laptop’s browser historyy—
resulted in charges against him. 1
Deleting browser historyy was also one of the charges against David
Kernell, the college student who hacked Sarah Palin’s e-mail account.
What’s chilling is that when Kernell cleared his browser, ran a disk
defragmenter, and deleted the Palin photos he had downloaded, he wasn’t
yyet under investigation. The message here is that in the United States yyou
are not allowed to erase anyything yyou do on yyour computer. Prosecutors
want to see yyour entire browser historyy.
