Query: As American as apple pie.

Make no mistake - the "Boston Massacre" and "BostonTea Party", while celebrated milestones on theroad to Independence, were riots. Rioting has beena popular mode of expression for the common manfrom the beginning, and no doubt will continue tobe.Gilje carefully traces the phenomenon from ourearliest roots to the present, finding four broadhistorical phases, with differing causes and,perhaps most importantly, differing levels ofviolence. The fourth, or latest, stage has beencharacterised by relatively mild violence - untilrecently.Admirably researched and very well written, Gilje's workis a welcome light into a dark corner of American life.Highly recommended.(The numerical rating above is a default settingwithin Amazon's format.
