Any really good books about a cop’s life? By the policeman, himself?

Joseph Wambaugh wrote several.

I just ordered a book I haven’t read yet , but sounds good it’s called Loose Units by Paul F. Verhoeven

Gotta go with Wambaugh. I’ve read everything he’s written.

Bihar Diaries by Amit Lodha, “Bihar Diaries narrates the thrilling account of how Amit Lodha arrested Vijay Samrat, one of Bihar’s most feared ganglords, notorious for extortion, kidnapping and the massacre of scores of people. The book follows the adrenaline-fuelled chase that took place across three states during Amit’s tenure as superintendent of police of Shekhpura, a sleepy mofussil town in Bihar.
How does Amit navigate between his many professional challenges and conquer his demons? What does he do when the ganglord comes after his family? Bihar Diaries captures vividly the battle of nerves between a dreaded outlaw and a young, urbane IPS officer.”
