The book by sociologist Neil Gerlach starts with a theoretical outline about possible fears of society about developments and results of biotechnologies, e.g. transgenic animals, genetically engineered food, possible demands for a right to normalcy ("new eugenics"), patenting genes, and "charismatic science." The next section deals with the "culture of the trace" and DNA fingerprinting in terms of criminal applications and the impact on judicial proceedings. This is put into the context of an apparently widespread and, in the eyes of the author, unrealistic fear of crime in Canada. It is argued that the use of DNA in legal contexts may lead to a "surveillance society."
