Two of these...concern the relationship between age and crime and the relationship between past and future criminal activity...serious students of crimemake it a point to carefully consider these issues....[this book] serves as anexemplar to all criminologists as to not only how to conduct sound research onkey criminological questions, but also to do so in a way that is careful not to gobeyond the reach of data.'
