The Application of the Central Limit Theorem and the Law of Large Numbers to Facial Soft Tissue Depths: T‐Table Robustness and Trends since 2008,

By pooling independent study means (), the T‐Tables use the central limit theorem and law of large numbers to average out study‐specific sampling bias and instrument errors and, in turn, triangulate upon human population means (μ). Since their first publication in 2008, new data from >2660 adults have been collected (c.30% of the original sample) making a review of the T‐Table's robustness timely. Updated grand means show that the new data have negligible impact on the previously published statistics: maximum change = 1.7 mm at gonion; and ≤1 mm at 93% of all landmarks measured. This confirms the utility of the 2008 T‐Table as a proxy to soft tissue depth population means and, together with updated sample sizes (8851 individuals at pogonion), earmarks the 2013 T‐Table as the premier mean facial soft tissue depth standard for craniofacial identification casework. The utility of the T‐Table, in comparison with shorths and 75‐shormaxes, is also discussed.

POSTAL 2 plays in US court - Schwarzenegger v. Entertainment Merchants Association

In an unprecedented legal development, the case of violence in video games has now reached the highest American court. The US Supreme Court is set to decide whether states can restrict minors from buying violent video games in the case of Schwarzenegger v. Entertainment Merchants Association. The decision could have serious implications on the future of First Amendment rights and children’s ’welfare. To resolve Schwarzenegger, the Justices will need to decide how much First Amendment protection should be extended to violent video games and whether minors have a greater constitutional right to violence than they do to obscenity.
