Hans Scholl: Reasons for graffiti campaign
After my first leaflet operation that was carried out by Schmorell and me in Munich in the night of January 28/29, 1943, I could not see that these leaflets had any effect whatever. I saw no response of any kind from anyone following this operation.
I therefore thought about what avenues of propaganda remained at my disposal. I hit upon the idea of writing slogans on the walls of houses.
