"He does do a lot of experiments. A lot of them I don't fully understand, but I'm certain he's not making bombs," said the suspect's father, Allen Mason"
Oh? How are you so certain? You just said you don't know what he's doing. Ergo, you don't know what he's doing.
I know, I know... Slashdotters will all side with the "experimenter", because geek. But it sounds like the police are acting based on evidence, while the defense is acting based on blind faith. In such cases, I side with evidence.
That's only true for the largest companies -- and even they won't be able to predict what they'll run out of.
Consider video/moviemaking. The big ones have "runners" to get what's needed. This service replaces them -- probably at a lower cost. But most production teams are too small to have a dedicated runner, so this service is a godsend.
