I think many people are well aware of all these news reports, and the general desire of terrorists to smuggle bombs onto airplanes.

But can you explain how moving those same bombs into the cargo hold makes us any safer? Don't we need to focus on detecting them in the first place?

Bear in mind that no planes have crashed as a result of terrorist bombs in recent years, while several have crashed as a result of (accidental) cargo hold fires... So there is evidence that bombs in the passenger cabin are actually safer.
