There isn't any death penalty in Germany, anyway not at humans.
Constitution-adversarial(verfassungsfeindliche)trees were executed some years ago.
You are certainly surprised, how can be a tree an enemy of the constitution or not?
Over sixty years ago trees were grown and you could recognize a swastika. But only from the air perspective.

Some years ago I had read from it. Now I have rediscovered the link , I was looking for a list where the in Germany forbidden symbols are listed.
When I had found the name constitution-adversarial trees, I had to laugh first time because trees behave normally very peacefully.
Much is forbidden in Germany because Neo-Nazis abuse these symbols. An example, in some schools clothes are forbidden, on which the number 18 is to be seen. Why?
The first letter of the alphabet is an A and the eighth an H. Perhaps this could be the abbreviation of the German head of state(1933-1945).
I am very glad for it we had the swastika and not knives and fork as nationality markings at that time. Were it would have been the cutlery, we must certainly eat with the fingers today. ;)
I find it well that the right-wing radicalism am fought but particularly the many bans remember me to this bad time.
