These scumbags were arrested, they can kiss their career in the Navy goodbye and are now likely to face serious criminal convictions.
As long as men are men these sort of nonsense is going to go on, whether one is in the military or a civvie on the street makes 0 difference, there is no rapist/molester gene that can be used to screen those prone to such offences nor does the Indian Military (nor any military in the world for that matter) conduct an analysis on whether an individual will be prone to these acts whilst in the military. People's mentality needs to change along with an improvement in the law enforcement's capabilities to detect and prosecute these crimes.
It is highly laughable that Pakistani members here like to portray India as the only nation on earth where sexual offences take place.
