A second article examines State and Federal laws that authorize the collection of DNA samples from persons who are arrested but have not yet been convicted of a crime, as well as debates and court cases that have ensued from these laws.

A fifth article presents the results of a rigorous evaluation of Chicago's CeaseFire program, which proved to reduce shootings in crime-plagued neighborhoods. A key component of the overall strategy was to use reformed ex-gang members as "violence interrupters" in interacting with gang leaders and members to develop alternatives to gun violence for dealing with conflict.
