West Europeans are racist, they may deny it themselves but a bully would rarely call himself a bully.
But
No mater what a person in Europe says, or whatever he does, what his religion is, what his background his or what motive he has
If you kill a person in a European country don't expect and the police know you killed him don't expect to sit at home. Zimmerman should have been arrested even if the kid he shot beat him up to a pulp, the police should not act like a judge and determine if Zimmerman is innocent or not.
Edit:
About the whole discussion of the police and what they did....
Their is a really good reason why the local officials have been replaced, it isn't because they where doing their job to well.
from what I heard they didn't question Zimmerman but had a interview;
they led the witnesses to certain answers in favour of Zimmerman, so a witness says A but cop says no it is B
Also when they where on the scene the cops didn't test Zimmerman for any alcohol, they did test the child who had tea and candy with him
Again the cops don't get replaced when they excel at their job
