The existing of crime may be a reason why we can’t call the world we are living in an “Utopia”. I believe everybody more or less may have some bad memories related to crimes. It’s a good thing to protect yourself if you know the crime situation of the city you are living in.
For this project, we want to mark the places where something have happened there to tell people be aware of the potential dangerous.
Also there's an mobile app could help people to check the status around themselves.
