I think those posters are way overstepping the mark. I don't mind the idea of promoting charity donations by claiming they are more effective than giving to beggars, but personally I'd like us to preserve the human institution whereby if somebody asks us for help, we consider giving it. Human relations are very nuanced, there might be good reasons why someone begs rather than turns to homelessness organisations. I'd hate to live in a country where everyone has the same robotic 'can't help you, you should report yourself to the police' response.
