Yusuf has a point, and if you ever get a chance of interacting with Dr. Kalia (Capt. Sarubh Kalia's father) you will realise other that assurances, there was nothing concrete done by the then NDA government on the issue. We took up the issue back in '09 and got in touch with Dr. Kalia, who also happens to be a forum member.
In case you personally want to get in touch with him, please visit this thread for details: Capt. Saurabh Kalia - an appeal and a tribute!
On the issue, I think Natrajan is right, this is a mentality that has grown on us Indians to forget and let it be and which then reflects on our politicians, be those of which ever background. I recall back when the incident happened pretty much everyone was up in rage, now most wont even know who Capt. Kalia was.
