In the digital age, investigations are more about following trails of bytes than breadcrumbs. But while there is inevitably more information than ever to work with, examining it can pose a slew of challenges. Today's investigators have to adhere to various e-discovery regulations, for instance, or navigate data privacy laws to collect evidence at home and aboard.

And then there is the question of the data itself. While one may be more likely to get at the truth of a matter with more data at hand, reviewing all that data poses a great challenge.

For Alex Southwell, partner at Gibson, Dunn & Crutcher and one of several speakers at Exiger's June 26 “How Data Analytics Can Transform Today's Complex Investigations” discussion, the biggest problem rests not with data or law, but with human reviewers themselves.
