Opinion- not necessarily the author's opinion, but their colleagues, who are people who are working for the New York Times, who extremely likely to be people who are not experts in art museum robberies.

This news is not something that is near to us or NYC at all, but is something that has been all over my news feed and social media feeds. Why this was in the news is likely largely due to the unusualness of the matter, that one of the most famous art museums in the art capital of the world was broken into, and is a place that is known to have lots of security in general. That leads to the next point of the prominence of the story, and how whether you are interested in art or not, almost everyone in America has heard of The Louvre, or at least some of the art that is in the museum, like the Mona Lisa.

This article may have come from a public relations statement about the robbery in general, but not necessarily as a way to promote the museum in general, since hearing about a robbery may make people feel that they are unsafe while being at the museum, and that there isn't enough security.

This wording sounds similar to an opinion rather than fact, where they are assuming what the reader is thinking.

This is interesting to say because how does this author know this? The thieves didn't say that they were specifically not looking for oil art pieces, but just that they went after the jewels first.
