Why would the intelligence community be involved with decision-making inside the department of justice?

And Obama's DoJ apparently decided not to pursue the case, why would we expect Biden's DoJ to come to a different conclusion?

It's also interesting that this case has so many overlapping conspiracy theories that I don't even know if my initial comment is downvoted by US patriots for suggesting that the case might be politically motivated (which is the assertion made by Assanges defence team and many human rights groups), or by Assange supporters for suggesting that there was no ongoing investigation in 2010 and the Swedish allegations were not a plot by the DoJ :)
