The initiator of the manifestation is Johan Ståhl. A few weeks ago he had enough of hearing news about violence, gang crime and car fires in the city - and decided to do something that sheds light on other things. It became a manifestation for a lighter Uppsala.

- Instead of demonstrating against something, we can manifest for something. This is a way for everyone living in Uppsala to stand up for each other and for their city, says Johan Ståhl.
