A quintessentially religious law, Shariah has set penalties, known as haddcalled exemplary punishments (Quran 5:38). These are performed in public to remind residents the wages of evil. Retribution is an important part of Muslim punishments, using the standard of Lex Talionis, ie eye for an eye, to measure punishment. For example, the murderer should be executed in the same manner his or her victim was dispatched. The Discretionary Punishments (tazir) are especially meant to return offenders to the gilded path of Allah.

Just hang them first then we will think of it next.

They should! Situation has already gone beyond control. It's good that all political parties came forward for stronger laws to deal with crime against women. They have also demanded more effective punishment in the rarest of the rare cases of sexual assault --- such as the one Delhi witnessed. Also there is a need to act sternly against every instance of eve teasing as these are the warning signals. Most of the eve-teasers are booked either under section 294 (obscene acts and songs) or 354 (assault or criminal force to woman with intent to outrage her modesty) of the Indian Penal Code, and both of sections are cognizable and bailable. Such crimes should be made non-bailable.

Even more stringent punishment will be taken by the govt.

Hope so
