A minor one but it’s bugging me.
CSI, of course, stands for Crime Scene Investigation, as in the shows CSI, CSI Miami, CSI New York (and, for all I know, CSI Peoria by now). One imagines that the shows are well researched. In the Law and Order series, however, it is always CSU (Crime Scene Unit). As these shows take place in New York it follows that either CSI New York is wrong or they are.
Which is the correct term?
