I take exception to his BTK killer. The K does not stand for killer so if you just say BTK you've missed an important aspect and if you say BTKer people are going to look at you all funny like and nobody's going to pay any attention to anything else you say. As for the emergency EPIRB rescue beacon, I'll grant him the emergency but the R is for Radio, not Rescue. If you say EPIR rescue B you've chopped the idea of an acronym all to behoozis and if you say EPIRB rescue you've totally compromised any hope of communicating. Fighting redundancy is like fighting the whole idea of communication. Let it be and spend your efforts on a fight worth fighting.
