The text is clear and concise, with chapters dedicated to describing different kinds of jobs police officers perform, what kind of training they need, the equipment they use, etc.  The color photos are well-chosen to support the text and are clearly captioned.  This is a high-interest topic for elementary students, and this volume provides plenty of substantive information, while breaking up the flow of information with enough photos, so as not to over-whelm young readers.  Solid, sturdy binding, too.
