The discussion centers on whether Attorney General Eric Holder should comment on legislation, specifically Arizona's immigration law, before thoroughly reading it. Concerns are raised about the pressures on Holder to respond without full familiarity with the law, suggesting that he likely relied on summaries from staff. Critics argue that this behavior is prevalent among politicians, leading to uninformed commentary and potential oversight of important details within legislation. The conversation highlights the issue of lengthy legal documents, which may discourage thorough reading and allow for hidden provisions, such as pork barrel projects, to be included unnoticed. The Arizona immigration law itself is noted to be relatively concise, approximately ten pages long, contrasting with the complexity of many legislative documents.
