言葉は、弾丸にもなる（ACジャパンCM） – YouTube

This is a commercial by AC Japan, a public corporation.

People from elementary school students to working adults are happily operating their smartphones. Listening to the sound effects, they seem to be typing some words. They then transmit the word, saying the onomatopoeia of a gunshot. Then other people suddenly fall down dead in their lives. So finally the viewer understands that what they were typing was a kind of slander.

It is not so uncommon nowadays to hear about people who have taken their lives because of slander. The reason why slander and defamation still persists is that it is difficult to connect the words on the Internet with the image of death. This commercial tries to connect the two images by using bullets as a direct metaphor for words.

It is now commonplace to see people looking at their phones and laughing alone or with friends. By showing this scene, the viewer is led to believe that the issue of slander has nothing to do with them.
