This was a screenshot I took of a news report. I won't reveal the identity of the news station, as journalistic grammar goofs are dime-a-dozen and no outlet is immune. Sadly.
I chuckled over the image of non-life threatening.
Interestingly enough, there are online discussions about whether the phrase should be written as nonlife-threatening or not life-threatening. No instances, though, where any grammar geek suggests non-life as an option.
