If you were a member of Congress or a lobbyist for a security equipment manufacturer, you'd see high costs as a benefit, not a problem. As long as the cost would result in profits for a (relative) few. I think our government would gladly pay Israeli-level security costs - if it could spend it on machinery made in the USA, rather than on salaries and training.

It sounds to me like the Israelis are the ones that have a process and who are devoted to their manuals. Every horror story we hear about the TSA seems to involve TSA agents not having a clue how to behave like civilized people, let alone effective security officers, in even the most mundane situations.
