It's sad to see homeless or drunk people in the street, but that's the worst I see.
I think eating healthy, exercising, having friends and a job does much more for our "safety" than ridiculous laws and surveillance.
I don't understand why people fear so much. Is it not possible to just refuse to fear? Be conscious about the effects it has. Talk about it. Why not just be brave and ignore the nonsense? Living with fear is no good life. We can't choose what happens in the world, but we can choose what we feel about it. We will die if we have to die. So what? It's not the end of the world.
edit: I remember seeing the tv in Finland. They play hours of crime-related series every day. What can you think of the world if you just see murders all day?
