Well, other than being a horrible idea, you've no idea how they would do that. The Bureau has excellent facilities for the likes of electronic intercepts and the tracking of criminals. Indeed, is the function it was set up for- legal co-ordination between sovereign worlds in the Republic is notoriously poor, with the Jedi being the only federal-level force and being far too few to follow all criminals individually. The Bureau has brought in a new structure where criminals are traced as they move between worlds (it;s full name is the Bureau of Immigration and Undesirables).
Their logistical help is what enabled the team you are now with to catch Kara Katai which in turn led to this mission you are now on... but it was you Jedi who took Katai down. Bureau agents trying that would have been shot to pieces. Tracking criminals and smugglers is one thing, but Dark Siders are quite another. Put simply and not wanting to sound arrogant (Well... maybe a bit...)... the Bureau aren't qualified to take them
