It's hard get a public service announcement about domestic violence right. We saw that earlier this year when a two-minute PSA, featuring Keira Knightley being hit, kicked, and shoved by a man, caused an uproar. Show violence and the whistle blowers will come; simply show a sad-faced woman and it might as well be a Midol ad. Now Germany is trying to curb domestic violence by covering windows with images of fake beating scenes and the message "looking away supports violence." For optimal impact, the ads are being placed over windows of highly visible apartment buildings. Anything unexpected will grab people's attention, but will that attention be good?
