One reporter acting questionably, even if one assumes poor intent, does not tar an entire group, any more than one doctor behaving poorly taints all doctors; or one teacher; or one auto mechanic...et al. I saw the report. I chuckled and moved on. What I didn't do was get my knickers into a knot over it.
As for "their" jobs, it is what their bosses say it is, not what I say it is, not what you say it is. Broadly speaking, that includes often being at the scene of some major news events. Destructive hurricanes fit the bill. A handful of curmudgeons don't change that reality. And you still haven't said what IS necessary and proper in your hypothetical scenario. Does it warrant having any correspondent there? A camera and technical crew? Who? Whose job, precisely, is it to cover such an event, and how should they cover it? With pictures? Video? Audio? Only wire services? Pool reporters? Is three the correct number of staff? Five? Twelve? What type of situation is deemed appropriate to send...whoever? And when may they be sent? How many hours after may they arrive to document the damage? Days?
The fact is the journalists going to such locations take abundant precautions. Can they prevent every unfortunate incident? No. That's the nature of life. But there is plenty that goes into preparing for such things that helps mitigate the risk, with some level of risk being part of the job. Sometimes it's the least risky-appearing situations that end tragically, because it was so out-of-the-blue.
We live in a visual world. As David so concisely noted, we are curious--well, most of us are. We react to images and sound. And we rely on people in "the media" to do the job of bringing us the types of information we--collectively--wish to see.
