Abstract
In their recent introduction to forensic linguistics, Coulthard & Johnson (2007) include a portrayal of the likelihood-ratio framework for the evaluation of forensic comparison evidence (pp. 203–207). This portrayal includes a number of inaccuracies. The present letter attempts to correct these inaccuracies.
