There is no transcript yet, so I am quoting submitted testimony, page 5, second paragraph:
"... the group found that there were far fewer legal impediments to information sharing between the law enforcement and intelligence communities than many people in both communities had thought, and the the principal obstacles were ones of agency culture and lack of understanding. There are simply no walls or restrictions on sharing the vast majority of counterterrorism information. There are no legal restrictions at all on the ability of members of the intelligence community to share intelligence information with each other."
Thanks, that certainly nails it.
