Maharashtra Home Minister RR Patil on Wednesday said there should be a timeframe to award punishment in terror cases and sought to know for how long the government should take care of Pakistani terrorist Ajmal Kasab, facing death penalty in the 26/11 case.

"Kasab has killed so many innocent people. For how many days, should we take care of him is the question doing rounds in my mind," he said while addressing a gathering at a book release function in Mumbai.
