Indiana state trooper at the forefront of the idea that cops need to be better at incorporating the online world into their patrols
Many police departments have computer crews that perform skillful forensic analysis
on hard drives and specialize in nailing online predators. Cohen's lectures are not for them
Instead he's trying to reach everyone else in law enforcement: beat cops, homicide detectives and other investigators who might otherwise think monitoring the Internet is not their responsibility
More and more, such boundaries don't make sense
Things people once wrote in private diaries now cascade through Web sites that stimulate free expression
and are open to anyone who comes looking.
"People under 25 tend to think about what is public versus private information differently from the rest of us, and that is great for law enforcement investigators," Cohen, 37, tells his audience
"Your computer usage is in some ways a window into your soul."
