Linus, Snoopy’s reflexes are 20 times faster than yours! Try it and see, Snoopy can make short work of you without doing any serious harm, and no jury in the world would convict him… he’s too cute!
A panel looks like an instant in time, but actually represents a period of time. For example, all the words uttered in panel 1 took several seconds. So mom started her sentence as dad was pushing open the door, and dad answered after he stepped in. We’re only given one visual “instant” for each panel to represent the whole story part of that panel.
Sad news indeed.
