I am a bit confused by your stressing the access is read-only. Isn't that obviously given (apologies for the redundant words, but I really don't know how to convey my confusion). For what purpose they could ever be given a write access to the hundreds of federal databases they are supposed to analyze?

Also, if they don't have the manpower to go over the data one by one then they don't have the power to go over them in parallel. When you say "parallelising the work" what exactly does that mean? What is it specifically that they are "parallelising"? Is there an engineer/analyst looking at multiple screens simultaneously and arriving conclusions for multiple agencies at the same time?
