WHOM SHOULD A LAYMAN BELIEVE?

"To talk about the horrors of lead poisoning in the context of hearings on lead in gasoline is analogous to talking about the horrors of gassing World War I soldiers at a hearing on... chlorine to purify drinking water."

"The problem in young children is even worse because lead can cause irreversible brain damage... Because of the ubiquity of lead contamination, it is unreasonable to consider any additional exposure to lead from auto emissions."

The intelligent layman will look for what has not been said. Nowhere in his 500-word letter to the Wall St. J. (9/14) did Cavalieri use the word "paint" or note the relative importance of different sources. The "additional exposure" argument is well known to readers from the case of radioactivity.
