I think the point is the framing, and it’s not really that subtle. Yes burglary has a technical definition but it’s commonly assumed that the underlying motivation of burglars is theft (because it almost always is).
The FoxNews story emphasizes the burglary aspect of the incident, even putting that in the headline:
The same story on CNN has a completely different framing:
Emphasis on the vandalism, not the burglary. The CNN story does have the same quotes from the authorities referring to burglaries, and even uses “burglars” in the first paragraph that describes the incidents, but it provides much more context.
For example, while the Fox story makes no mention of the similar attacks in NC last month, or of the FBI warning, CNN goes into detail about this, e.g.,
The bureau in a November 22 bulletin warned of reports of threats to electricity infrastructure by people espousing racially or ethnically motivated extremist ideology “to create civil disorder and inspire further violence,” according to the alert sent to private industry.
I don’t think it’s surprising at this point that FoxNews is doing everything possible to downplay the threat of rightwing extremist terrorism.
