I just saw some short clips from a movie (I presume), Molly Shannon was the only one in the cast I recognized. It was a suburban setting, some guy gets shot in the back at a neighborhood barbeque, later she and a 10-year-old boy both have handguns and are in a standoff with law enforcement, and a sharpshooter picks her off (not immediately dead). There’s some young guy associated with law enforcement who was probably the star, but I didn’t recognize him. I think this must be in the last, say, 10 years, based on her appearance, but I’m not certain. I couldn’t find it in her IMDb listing.
There was a narrator describing events, rather than audio from the clips, but unfortunately it was in a foreign language, and I never saw anything to identify the movie. It all looked pretty intense, and I wondered if the movie was worth watching.
