" But Gorelick, like other researchers, traced the statutes limiting intelligence sharing to the administrations of Ronald Reagan and George H. W. Bush in the 1980s. Under those presidents, intelligence sharing was permitted for spying on foreign suspects but not criminal prosecutions."
Yes it has a bit of truth, but the truth that it contains is irrelevant to how Gorelick and her superiors misused the law to do their own bidding.
It's not that the idea of the wall was bad; it's that Gorelick, probably under the Clinton’s say so, built the wall: higher than what the law required, managing to completely obstruct America's ability to deal with terrorist whose source was outside of America.
Also; by Gorelick requiring that the foreign emanating terrorist who had committed or were planning to commit acts of terror against the USA, be prosecuted through Americas legal system, she severed any ability of the CIA to not only get information from such person in the domestic legal system, but also completely disallowed for the legal system to get information from the CIA. This was not so before Gorelick insisted that the wall be built higher than the law required, and before gorelick required that cases be classified as domestic or international bat the very beginning of the case, often before there was enough information available to anyone, except the Clinton's as to what the real nature of the case was.
