  2. In a study to compare rates in different populations the absolute rates are less important, the primary concern being to avoid systematic bias in the comparisons. Assessment of repeatability may be built into a study - a sample of people undergoing a second examination or a sample of radiographs, blood samples, and so on being tested in duplicate.
  3. A case might be classified as suspected or probable while waiting for the laboratory results to become available.

Based on the idea that all individuals may suddenly and unexpectedly lose control when words are spoken or events occur, jurisdictions differ on whether this should be allowed to excuse liability or merely mitigate to a lesser offense such as manslaughterand under which circumstances this defense can be used. However, the law retains explicit exceptions which prohibit the prosecution "of any person for conduct relating to an abortion," "of any person for any medical treatment," or "of any woman with respect to her unborn child," thereby preserving the right to an abortion stemming from Roe v.
