You want the book Junk Science and the American Criminal Justice System [1] by Chris Fabricant, the Innocence Project's Director of Strategic Litigation.
The book is an approachable, anecdotal tour of some of the significant issues with each major sub-speciality within forensic science.
The Innocence Project uses DNA testing to prove convicted criminals are actually completely innocent of everything, them undergoes the massive legal battle required to have a chance of going from conclusive evidence of innocence to release in the American Justice System. The are reasonable quibbles with their methods on the margin, but taken as a whole their work is an amazing contribution to society.
Edit: I imagine some people might be skeptical that there's an uphill battle after conclusive evidence of innocence. Take a look at Shinn v Ramirez. Mark Brnovich, the Arizona Solicitor General, successfully convinced the Supreme Court to tell a federal judge they couldn't look at Ramirez's evidence he's innocent. Notably Brnovich said "innocence isn’t enough here" [2][3].
