The truth is that Law Enforcement investigations are currently taking information from dozens of silos/databases, manually copy&pasting them into Excel and Word and then finally making a pdf or powerpoint to share the results. This is obviously a really inefficient way to do things and wastes a lot of taxpayer money.
A technical solution that would allow LE to crosslink data they already have is a no-brainer.
P.S: Very biased view, as I'm building/selling exactly this tool :)
