Here’s a terrifying story; apparently US nuclear facilities are protected not so much by “guards with guns”, but rather “high-tech” webs of cameras and sensors. Which is great. So long as said “high-tech web” is functioning and someone is monitoring it. Which it’s not and they aren’t.
Fortunately, thus far the only people who’ve exploited this lax security were a bunch of retiree peace activists. Thus far.
How did this happen? If your answer is something like, “Hm. I bet they hired private contractors to do security, and said contractors promptly began cutting costs” then ding ding ding ding! You’ve been paying attention.
There are some things profit-driven industries are great at, like making socks and smartphones. For others? Seemingly not so much, hey.
