Yeah, Lee Child is apparently not big on research for his novels. In addition to the items you mentioned, many of the location descriptions are pretty far off. Most of them are still decent reads though, even if you must suspend disbelief to get through them.I've been letting my mind rot reading Jack Reacher books by Lee Child (I am on Reacher #17).
I have a few criticisms. If one was never in the Army or Army National Guard (as I was), you probably won't notice the numerous military inaccuracies. Also, Lee Child is British and it shows in some of his word choice and phrases. Also, if you're not into guns, you probably won't notice the errors- like, in "The Affair" where Jack "weighs" a cartridge case in his hand to determine whether it is a .223 Rem or a 5.56 NATO (to determine whether it was fired by a soldier of a civilian)...ignoring the following facts: they would have a head stamp, while military would only use 5.56 civilians could use either, the weight difference is something like a bit more than a tenth of a gram. There's also a lot of referring to the 9mm as "powerful"...which a Brit would do, I guess. Reacher has killed how many people and NOT ONCE has he ever had to explain this to a prosecutor and hardly ever to cops?
Anyhoo- with all that....I'm sure I'll finish the series...I've got the Jack Reacher monkey on my back.
