Forensic approach towards criminal use of mercury in domestic violence

The prevalence of criminal cases against women is not first-hand with statistical data from the National Crime Records Bureau in India proclaiming an even rise in cases of domestic violence. Despite numerous laws to protect women against various crimes including rape, sexual harassment, dowry death, etc., there is less respite from violence toward women in India. Indian society needs to stand up and address the existence of many socio-cultural reasons for crime against women apart from literacy to lower these crime statistics. Forensic experts play a pivotal role in the scientific examination of evidence to support the criminal justice system which in the end affects the lives of millions of female victims.
