As a group of hoodlums and gangsters, the K & A Gang is not well-developed, even by the standards of other Irish or WASP gangs. Hornblum's research identifies a lot of the prominent figures and their interrelations with other hoodlums. The strength of the book is the sources. The book is based almost entirely on interviews with the criminals themselves, and possibly the lawmen chasing them. The result is that the book largely repeats whatever they say without much to corroborate or contradict them. This is more pronounced in the later chapters that are entirely based on Kripplebauer's recollections.
The K&A Gang was a predominantly Irish group of tough guys who burgled the homes of rich people along the Eastern Coast in the 1950s and 1960s. They operated in crews of four men with 2 searchers, one driver, and one watchman. They called it production work because they treated it like a factory line work. There was very little organization or diversified rackets. They were mostly burglars working in tight-knit groups with crew chiefs including Kripplebauer, Effie Burke, Willie Sears, Ted Wigerman, and John Berkery. Hornblum does not offer any evidence of how the crews operated in relation to each other or how they interacted with other crime groups, like the Italians. They are more Ocean's Eleven and less Boon Dock Saints.
Most f the book is anecdotal in nature. Hornblum scored enormous success in getting many of the guys to open up about their lives of crime. Most were cautious about specifics or anything violent, making the book full of stories about Effie Burke pooping in front yards or similar hi jinks. The stories add authenticity and humor while saying little about the gang. Another common theme was Charlie Devlin, who was not really part of the gang, but something of a legend for his brand of violence in the K&A neighborhood. Everyone that Hornblum interviewed had something to say about Devlin. Devlin's demise also bespoke that the gangsters could be violent, despite their claims that they never wanted to hurt anybody. The hint of violence that permeated the gang (like any other Irish gang) was focused inwardly. The gangsters killed themselves more often than outsiders. One weakness of the book was the lack of violence and mayhem that typically goes along with the Irish gangs as they self-destruct.
There is a single chapter on the cops. Hornblum also claims that he interviewed a number of former lawmen who pursued the K&A Gang. However, there is almost no first-person perspective in the book from the lawmen. The chapter does a good job in describing their response and pursuit of the gangsters; but there are no anecdotes from FBI Agent Bill Skarbeck talking about how tough Effie Burke was, or how violent Kripplebauer was, or how he especially loathed any other hoodlum. The chapter is lacking the color that highlights the rest of the book.
Kripplebauer's recollections occupy the later chapters of the book. Like so many hoodlums who tell their stories, it is full of self-pity; but also surprisingly upbeat and positive as Kripplebauer fought the system so he would have a life after prison unlike so many of his colleagues. There are hints of extreme violence, but Hornblum passes them off as hyperbole and fantasy rather than the possibility that Kripplebauer was serious and experienced in violence. That is the problem of not having corroborating sources, even from the lawmen. It is a bit curious that Hornblum never cites the PA Crime Commission reports or FBI files. Both are relatively easy to obtain and offer material that could be corroborating.
Overall, the book portrays the gangsters like leisure criminals more fun and gruff rather than dangerous. The stories mostly come from the criminals themselves, so they are heavily biased in portraying themselves as gentlemen rather than cutthroats. In a few cases the violent side of the gang shines forth, like the Pottsville caper or the sudden and violent death of crew chief Willie Sears. Otherwise, the violence surrounding the gang is shouldered on non-gang members, giving them a mythical status as glowing as the gangsters themselves. The book does not say much about the gang except to say they were burglars and identify the most prominent members, which is a draw-back. But otherwise, it is extremely rare for so many former members to open up about their lives.
