The news does seem to overdose on distraught people, especially when tornadoes hit and destroy their homes. I see your point, though. The newspeople never almost never put composed homeowners on camera, and it almost strikes you as a cliche. Another cliche: sad music slathered over local news broadcasts, as if we had to be telegraphed to feel bad. We already do.
Of course, when you have particularly senseless violent acts like this, and horrible injuries, a lot less people will be holding it together. But I agree the news needs to be cognizant and not just zoom into every single frantic emotional breakdown.
