London Police say: if you hear something, say something.
"Nearly 1 in 5 murders in London are the result of domestic violence," claims this interactive video via the city's Metropolitan Police. It's part of a new campaign tagged, "You make the call. We'll make it stop." It opens on a man reading who is interrupted by the noise of an increasing violent disturbance in the next flat. You are prompted to click a box "if you think you should call 999 (the UK's 911)." If you do click, you're taken to another video where the man calls, and the police show up. If you don't click, well, it doesn't sound good. More info on the campaign here. Previously in: domestic violence awareness advertising.
