There is a constant ebb and flow between more sharing of information and less sharing of information. Bad things happen because of not sharing enough intel (eg. the 9/11 report)? Time to loosen restrictions. Bad things happen because of overly lax sharing of information (eg. Manning)? Time to lock things down. Both postures have costs and benefits that are difficult to quantify. This tends to cause knee-jerk reactions based on the latest crisis.
