Ennet House facts and Ewell's tattoo taxonomy
That over 60% of all persons arrested for drug-and alcohol-related offenses report being sexually abused as children, with two-thirds of the remaining 40% reporting that they cannot remember their childhoods in sufficient detail to report one way or the other on abuse.
Context
One item in the second-person catalog of "exotic new facts" you acquire around Ennet House: mass amnesia as a baseline condition of the addicted population — a quarter of everybody arrested can't retrieve their own childhood well enough to say whether it was abusive. Pairs with Pat's Walpole datum at p. 465: the addict's past is a blank at both ends. (The odd "drug-and" spacing is carried as found.)
