Yeah,there is a lot of crime helding in Mumbai because of police intelligence in Mumbai city these days is very weak and poor.The whole intelligence set-up in Mumbai as well as across other parts of the country is run by ineffective and inefficient officers..So in the presence of these kind of activities how can we prevent from the crime..and also a large range of crimes are helding in Mumbai due to population and lack of earning fields..so most of the people goes for crime to earn money and to survive in that big city..
