Book review please: The Last Hundred Yards by John Poole

[Rifleman]

1) Who's read it?

2) What did you think of it?

3) Is it a worthwhile read for police officers with things like active shooters, baricaded suspects, high risk warrant service, etc., in mind (Common sense and gut hunch says that it would be just for principals, but I want to know what people who've read it say).

The Amazon reviews were favorable but I wanted to get the opinion of boardmembers here.
