Who killed Hemant Karkare?

Karkare, Additional Commissioner of Police Ashok Kamte and Inspector Vijay Salaskar were killed by terrorists near Cama hospital on the night of November 26 when they were chasing terrorists. Who is responsible for their deaths? The Government or the terrorists?
As per a report on CNN-IBN, the bullet proof vest worn by the slain Chief of Maharashtra’s Anti Terrorism Squad offered no protection to him. The autopsy report says there were eight bullet marks on Karkare's body: four on the top of the right shoulder, one in on the back of the right shoulder and three on the right chest. One bullet was found in his left kidney and another in the right of his liver.
Apparently, the samples of the vest had failed trials at a police firing range. Yet they were procured and somebody laughed all the way to the bank.
This is the result of almost all government bodies who float a tender for supplies and select the cheapest product – quality be damned, as long as it is to be used by somebody else.
And now the vest worn by the hero is ‘lost’. Nobody can find it!
How sad is that?
