Where is our law? Where is women's security?

Hi,

I am joining this forum only because to know all of you the Barasat condition. I am very much disappointed . I am a lady. A woman came suddenly and bit my back suddenly and then I went to police station they do not help me at that time then also went gov hospital for physical checkup . I have still pain in my head. It happen infront of my house in Barasat. May I know from where this woman got power to attack me? Where is our neighborhood ? Where is our law ? How it possible that anyone bit anytime? I need help. I am afraid if it is happens infront of my house then it can happens me at anywhere anytime ? Where is our law? Give me some suggestion. What should I do?
