Most crimes in Washington are committed from Friday through Sunday. Almost everyone has a two-day weekend, and the drinking and celebrating begins Friday night.

The First, Second, Third and Thirteenth Police precincts account for 57 percent of all serious crimes. The First is “downtown,” with tourists, transients and night life. The others are predominantly Negro.

Among the more profitable of the organized crimes are these:

Housebreaking, comparatively easy because of the large number of private homes and two- and three-story detached apartment buildings. The stolen goods are fenced in East Baltimore Street, Baltimore.

Auto thefts, growing more serious.

Bank robberies, not uncommon.

Pickpockets and cold-finger men find easy loot at the countless cocktail parties and other functions constantly given by lobbyists, conventioneers and diplomats. It is a cinch to crash these. Jewel-thieves have rich pastures. Social climbers and ambassadors’ women are loaded with rocks and constantly display them. A big gem haul is sent to Holland for recutting, via reverse channels used by the Mafia to smuggle dope. The reset ice is smuggled back.

Because of the ease with which fixes are maneuvered, the lenient sentences, the failure of local courts to extra-penalize repeaters, Washington is indeed a picnic-pasture for crooks from all over the country. When other places get too hot to hold them, they hop a rattler for the capital.

The pickings are easy. The payoff is high. The risks are minimal. The burg is a pushover.
