This is happening b'coz of the misrule of commies for lat 20 years. Bengali's themseleves are responsible for this. They should have kicked out commies out of power atleast once in last 20 years. While other states were marching ahead,Bengal was marching towards anrachy. First the illegal Bangaladeshi's have to be kicked out of our nation, then only Bengal see some development. Otherwise this chaos will continue.
