I completely do not agree, if the same people are allowed to run an organisation in the same famous compound, thats not the same as banning them, doesn't wash. LET mediamen complaining to media that they can't operate is just that, PR. I know a pakistani journalist who had got JUD collection camp from his locality in lahore removed for inciting hatred against india (he's also commented on it in certain respected blogs too, need link?), so anyone who wanted to go beyond 'plausible deniability' knew what sort of org they were running,
Organization was banned and leadership that formed JuD has yet to be shown to have been involved in Mumbai. So yes, so far most of the controls Pakistan put in place to restrain the JuD have worked. The controls on the LeT failed, and Pakistan is therefore taking stronger action against them this time.
As far as 'inciting hatred against India', protected by freedom of speech. There are organizations in India, elected to parliament even, that I would argue 'incite hatred against Pakistan'.
should pakistan have 'merely gone along' (what i call - done its sovereign duty of stopping non state actors from attacking neighboring countries) to stop the murder of civilians, YES.
Your argument is a non-sequitur - You suggest that Pakistan had a responsibility for stopping the perpetrators of the Mumbai attacks from carrying it out - of course Pakistan had that responsibility, just like any police organization has a responsibility to prevent crime, but crime occurs despite the best efforts of law enforcement. Pakistan did not know Mumbai was going to take place.
Pakistan has helped almost eliminated cross-LoC infiltration and the insurgency in Kashmir, and it has done so for several years now. That indicates the level of control Pakistan exercised over these groups in order to prevent any acts that would vitiate the atmosphere (remember that the two nations were engaging in a very positive back channel dialog).
A proper investigation was done and evidence handed over, as was promised by indians, however ajmal kasab's name and address were public domain almost immediately, what stopped pakistan from doing preliminary examinations (if done,why lies were told on BBC?) to quicky apprehend the perpetrators so that they did not get time to cover their tracks? Mind you, Zardari did not say he did not know Ajmal's name, he said he did not 'think' Ajmal was pakistani.
India used the excuse of a 'completing a proper investigation', which is fine, but why then expect Pakistan to act without providing any proper evidence to base its own investigation on? It is absurd to suggest that Pakistan take action on the basis of media reports, and it is absurd to suggest that because Pakistan did not take action on the basis of media reports, and waited till India completed investigations and shared information, that Pakistan was somehow 'hiding Ajmal's tracks'.
Whether Pakistan investigated or not on the basis of media reports is irrelevant - what is important is that once evidence related to the perpetrators was shared, Pakistan acted. You cannot construct a case in court based on, "well I arrested so and so because the Times of India quoted anonymous GoI sources as saying he was involved".
If India was concerned about the perpetrators getting away, it should have shared its preliminary findings immediately and through official channels with Pakistan. Pakistan was the one continuously calling for a joint investigation and immediate information sharing. You cannot accuse Pakistan of 'delaying' or 'hiding things' when our position was clear from the get go and India was the one refusing to cooperate.
LET's PR is no evidence. Yes the incidents in Kashmir did fall, yes 26-11 happened, so was it a case of controlling the tap as per requirement?
No one can prevent a hundred percent of crimes - Mumbai fell into the category of crimes that slipped under the radar.
I don't agree pakistan is not responsible for creating the monster of LET (call it JUD if you want), its just against all available data. Their main office was not shut down, who's responsible?
I agree with the last para, though that does not automatically rule out institutional role.
Now you are making a different argument than earlier - Pakistan may have created the LeT to fight Indian occupation of Kashmir, and Pakistan acted to significantly limit the groups activities and control them after the parliament attacks, but the argument raised was that Pakistan was responsible for the Mumbai attacks, which I disagree with.
Pakistan is responsible in terms of prosecuting any and all people involved in that attack within Pakistan, and ensuring that those people and their organization do not have an opportunity to do so again.
