Eric Immesberger, who bravely went undercover posing as a hit man for 21 years at the Bureau of Alcohol, Tobacco, Firearms and Explosives, discovered murder-for-hire plots are more like a slapstick comedy of errors than a slick gangster movie. From weapons trafficking to disorganized criminal crews, his 21-year saga ended in 2019 leaving him with plenty of evidence—mostly from clients tripping over their own unrealistic hit plans and panic attacks. Instead of clean, professional deals, Immesberger saw frantic phone calls and botched requests that made police interventions easier and murders less frequent. Proof that crime doesn't pay well in competence.
