Well arien first of all there isnt any proof yet and as far as the arrest of LET members its an internal thing dont try to link it with that incidence.
I will suggest you to read about LET and specially about thier agenda they never hide thier identities or believe in disguise you may refer to Manmohan's trip to Jammu when two LET fighters were firing from top of the mountain killing 16 soldiers and ultimately thier lives also but not for a single incidence they denied thier actions.

For the sake of arguments if i agree that those guys were LET members then simply settling the Kashmir issue as per the resolution of UN would save India future from these incidence.

Anyway today you have elections and both parties are bagging votes playing smart on this issue.

what about two police officers arrested yesterday. This puzzle is a lot bigger then our imagination.

And let me tell you one thing now India is deploying thier army in Afghanistan i dont know whether your media is covering it or no but you are opening another chapter with Taliban and once you are on with Taliban you have to pay the price in dead bodies like America and Pakistan.

Keep a note of it and I am not going anywhere.
