>>7265443Anon is right, this would get busted up in America. It takes only one out of 10000 people to fuck something like this up. The "me me me me fuck you I got mine" mentality of the US is what causes this. In Japan, their collective mindset usually prevents something like this from happening.
Graffiti and any kind of defacement of property for any reason should be dealt with more harshly, that would be the key, but many would go "hurr durr why you not arresting da killers".
