Some "....matters....ought to be really state responsibilities, particularly in the area of prevention where we're dealing, again, with concerns about home-grown terrorism. In many cases, the challenges are what we would call "low-signature threats" -- threats that may not be detectable from spies and satellites, but require community-based policing and community-based knowledge to detect and deter and prevent threats before they come into effect. Because of that....we don't want to have the federal government become the choke point to which all this information has to pass before action takes place. That's why we're supporting fusion centers, including fusion centers with responders as well as police officials, so that states and localities can take action quickly to address issues. Now, we want to be able to have visibility into that, we want to share information up and down, but we don't want to slow up the process".
