The selection process has been powerful enough to produce one indisputable outcome: the family is a universal human institution. . . . In virtually every society into which historians or anthropologists have inquired, one finds people living together on the basis of kinship ties and having responsibility for raising children. . . .

Police ought to protect communities as well as individuals.... Just as physicians now recognize the importance of fostering health rather than simply treating illness, so the police - and the rest of us - ought to recognize the importance of maintaining, intact, communities without broken windows.
