I would say that there are probably two elements. Mr. McRoberts might want to elaborate as well.
One is the restraints and obstacles that have been reported to us, legal and otherwise, in privacy legislation, which people are claiming will preclude them from sharing information. The Department of Justice really needs to resolve those issues so as to be clear that there are legal obstacles. Then they have to be resolved, perhaps even through changes to certain legislation. Privacy concerns need to be addressed. Those obstacles to sharing information that people see need to be resolved.
The second one, I think, is the secure system they are working on so that they can exchange information. Systems don't solve all problems. We all know that. It's the people who put the information into the system. Hopefully, if the agencies and departments all agree to collaborate on this, that will send a signal, as well, that they should be sharing information.
