His detention was reportedly symbolic rather than actual; with LET visitors, internet access and the like. As we know, especially for India, symbols are important.
David,

Symbols are not important in India.

The dispensation of law as per the criminal code, rules and procedure are.

In India is you are in prison, then you do not get the privileges of the open society at large.

Lakhvi has all facilities of open society available to him while in Jail and he also fathered a child in Jail.

I wonder if that is symbols or miscarriage of justice.

Which country allows a terrorist organiser such facilities?

I am sure none in the West.

The Prosecution, it is said, did not present the case well leaving loopholes that the Pakistani Judges exploited to free this man.
