A Syrian refugee in Bingen, Germany set fire to the migrant shelter where he lived, and spray-painted a few swastikas to mislead the police:
You call that a swastika? Pathetic.
Take it from me: The secret to spray-painting swastikas is to spray the central cross first. If you're aiming for authenticity, tilt it 45 degrees to make an 'X' -- that's now the Nazis did it. Then you simply add some hooks at 90-degree angles. Bingo! It's not called a 'hook-cross' (Hakenkreuz) in German for nothing.
I'll be expecting much better work from now on, Kameraden.
