Why is hard nut Parrikar soft on illegal mining?

Opposition leader Manohar Parrikar one of the champion crusaders against illegal mining has, for reasons best known to him, has fallen short of naming the culprits behind the illegal mining.
The irony though is that illegal mining also existed during his tenure as the chief minister of Goa between 2002 and 2005.
According to him, the Goa government lost royalty on 1 cr tonne of mining export between 2002 and 2005, which the Public Accounts Committee (PAC), is inquiring into.
Parrikar, who is the chairman of the PAC, says the mining department has no explanation on the loss of royalty.
However, when it was pointed out to him that during this period he was himself the chief minister – what came out was surprising.
First instantly Parrikar backtracked that the loss was huge. “During those days illegal mining was not so huge and the royalty was paltry @ Rs 30 per tonne. So the loss would be around 25 to 30 cr.”
Then he said “even during my chief ministership, the mining minister was the same.”
Does that mean he is blaming Digambar Kamat for flourishing of illegal mines and loss of royalty? No, says Parrikar.
“It is you who is interpreting not me, I have not named anyone,” he says.
SO why is he letting Kamat off the hook?
Recently, a report blamed Parrikar for going soft on the Congress leaders and with the way the former chief minister has replied to the above queries has left one guessing – does Parrikar really want to raise the issue of illegal mining in the state? Or is he only paying lip service?
If he was so concerned about the illegal mining why didn’t he take action during his tenure?
He has instead vigorously accused police inspectors and other mines department officials for the plunder.
One question we would like to ask is, does Parrikar want the common man to believe that police inspectors and mining officials are only responsible for illegal mining running into crores without political backing.
Or is he giving a clean chit to politicians for the illegal mining menace?
