Mugging in city

Law and order has deteriorated severely in the capital. Almost everyone I know living in the capital, has an experience of getting mugged. I was mugged twice this year in the city's College Gate area. One of my friends was not only mugged but also physically attacked by the muggers as he refused to give in to their demands. He is still suffering from severe injuries. The incidents of mugging occur in daytime also. We are never safe while commuting in the city.
Whose duty is it to save us from this lurking danger?
