This is new to me. What bit of the science do DNA profiling outfits get wrong? How can one tell who is following protocols for well conducted science? What should one do in order to get good DNA results? How do I know that historians are not using the same outfits - or at least the same laboratories? You need to show that 'this section of DNA profiling is BAD because of such-and-such reason' but that 'this section of DNA profiling is GOOD because of such-and-such reason'.
