I think that it’s probably wrong, in almost all situations, to use a dictionary in the courtroom. Dictionary definitions are written with a lot of things in mind, but rigorously circumscribing the exact meanings and connotations of terms is not usually one of them…It’s easy to stack the deck by finding a definition that does or does not highlight a nuance that you’re interested in.
