Looking for books about some of the unsavory things the government has done

Mostly I'm thinking of the US/UK/Canada, and cold-war/war-on-terror/injustice towards indigenous populations sort of stuff, but that's certainly not all I'm open to. Other governments and contexts are definitely still things I'd like to read about.

I'm looking for something well-researched, written by someone who is NOT right wing, maga, or q-anon affiliated, and explains an event or prolonged undertaking that was ethically problematic, outright abhorrent, incompetent, or negligent, which was done by, with the aid of, or under the instruction of some part of the government (military, cia, kgb, etc).

It doesn't need to be the easiest to read (Imo I'd rather it be tough to decipher, convoluted, or have "too much" information than for it to leave something out or simplify the situation, if that makes sense), I don't care about the length really.

Other than that, ik it's not the most specific parameters, but I figure this way I'll get a wider variety of things to learn about.

~~(Any type of recommendation is welcome, but something I would be especially interested in is if anyone knows about books or info resources *specifically* about US military installations linked to spikes in cancers or birth defects or other medical issues due to whatever testing or experiments went on there. I have a personal connection to some possible effects from that sort of thing and want to know all I can in that regard)
