Gandhi's Assassination Case to Be Re-Opened?

The BJP Rajyasabha MP Subramanian Swamy wants Mahatma Gandhi's assassination case re-opened as he expresses some doubts on the day when Gandhi was assassinated.

"Page 52 quotes Associated Press International journo: he heard at 5.05 pm 4 shots [not 3 as PP in Court later told court]. Godse deposed he fired only 2. Same API journalist said Gandhi declared dead in Birla House at 5.40PM i.e., he was alive for 35 mins.  

1st question: Why no post mortem or autopsy on Gandhiji's body? 2nd : Why Abha and Manu as direct eyewitnesses not questioned in court? 3rd: How many empty chambers in Godse's revolver? Italian revolver "untraceable"!! Why? We need to re-open the case," Subramanian Swamy tweeted.
