Well whether this happens or not, but we come across these things daily and sometimes we overlook, ignore, or don't realise them at all... so why are we scared and for what. this is something similar to -
1) your corporate emails are tracked and stored (or by law for 5-10 years at least depending on which country you reside) by your company
2) your web traffic is monitored by your company
3) your movements are monitored by the surveillance camera's, whether you are in public transport, walking down the road, google street maps(
there is nothing wrong according to the district courts in the USA - lots of them here), the list goes on...
4) phones(including some latest VoIP providers) are tapped (whether you have been told or not) by the government departments. Once somebody is caught/exposed then the officials will say this person was under surveillance for so and so long ;-)
5) free public email providers do keep record of your emails too
6) every country has an internet gateway and they keep track of your browing history too
7) every ISP keep track of your downloads including mp3, + ;-), etc....
mobile companies keep track of all the calls/sms/emails/mms, etc - (or by law at least for 5-10 years again depending on which country you reside)
9) satellite phone communications are tracked and recorded.
10) the list goes on...
Some of them are easily justifiable and we need to have them and accept the fact that when we don't have these in place we land up in to blame culture.
How did the terrorists communicate, by email/phone/etc. do we have any records? NO. Why not?
Another important thing that we need to bear in mind that it becomes very very diffiult (no impossible though) to gather evidence across the country. This may be because of political pressure, Bureaucracy, red-tapism,etc..
As far as Indian government keeping tracking of all the emails from black berry, so what? all countries do. if you haven't done anything wrong then nothing stops you - but make sure you keep you blackberry in your possession and not give it to the ter.......t ;-)
I agree with Abhishekjha government should do more in the areas he mentioned, but there is quite a lot of things that needs doing, traffic jams ;-), including the dirty election game which is ongoing and will go on forever.
Thats my contribution.
