Crime has its own cycles,a magazine reported some years ago.Police records that

were studied for five years from over 2,400 cities and towns show a surprising link between changes in the seasons and crime patterns.

The pattern of crime has varied very little over a long period of years.Murder reaches its high during July and August,as do rape and other violent attacks.Murder,moreover,is more than seasonal:it is a weekend crime.It is also a nighttime crime:62 percent of murders are committed between 6 p.m. and 6 a.m.

Unlike the summer high in crimes of bodily harm,burglary has a different cycle.You are most likely to be robbed between 6 p.m. and 2 a.m. on a Saturday night in

December,January,or February.What is the most uncriminal month of all?May—except for one strange statistic.More dog bites are reported in this month than in any other month of the year.
