"The family of the Hyderabad doctor will not have to wait for justice for seven years like us. Police did the right thing," he said.
Congress leader and Lok Sabha member Shashi Tharoor, however, said extra judicial killings were not acceptable.
"Agree in principle. We need to know more, for instance if the criminals were armed, the police may have been justified in opening fire preemptively. Until details emerge we should not rush to condemn. But extra-judicial killings are otherwise unacceptable in a society of laws," he tweeted.
Rekha Sharma, National Commission for Women chief, said she was happy that the perpetrators were dead, but justice should have been done through proper legal channels, she said.
