Anti-DV PSA from Amnesty International Portugal.
It may be a translation thing but, generally when you wash your hands of something you are ignoring no? So wash your hands of denouncing DV? Of not denouncing it? Am I caught in a double negative? Regardless I think it is very clever.
I agree with Copyranter that it would quite the shock to stumble drunkenly into a bar bathroom and have blood come out of the dispenser.
