""There was a serial poisoner (Graham Young) in the last century who did the same thing, killing dozens over the years, with arsenic. And of course, terrorist bombers don't use guns either.""

I'm afraid, with the utmost respect Eliza, that you are equating apples and banjos.

Young killed over a period of years, and he managed that because he lived in a time before modern forensics. Anybody emulating him today wouldn't get past the first victim. As to terrorists and bombs, what is it, do you suppose, that the police and the bomb squad are trying to defuse at this fruitcake's residence?
