If you think that the two week SC/CS exercise is simply about security at the gates, you're sadly mistaken. The fact of the matter is that there are exercise/drill events taking place every day over that 2-week period, but they are done in such a way to minimize disruption to the base workforce as much as possible. Yesterday, there was an active shooter exercise event at one of our larger buildings. That exercise took several hours and served to test and further train our law enforcement personnel, fire and emergency services personnel and the workforce within the building on proper procedures. Other events will be less obvious, but are all equally important in keeping the base and its workforce safe. Is there or will there every be a 100% solution? No, there will not. However, doing nothing is not the answer.
Also during this two weeks...and throughout the year for that matter, "false credential" attempts are made on each gate, at random times on random days. Do they catch every one of them? No. They do catch most of them though and they get better all the time.
It's funny. Measures are put into place in order to better protect the base, i.e., closer scrutiny on credentials. The result is ALWAYS a slow down at the gates. That slow down results in the workforce bitching to their leadership and that leadership bitching to the base Commander. Base Commander relaxes the posture just a little bit to ease up on the traffic, i.e., scanning every 10th person v. every 5th, or whatever...and them some all knowing jack-wad (cough, cough) complains about being vulnerable. A never ending cycle that can't be won.
