perhaps not
just that DD driver but the ones related to this:
one of my working theories - a
nd jmo imo and I am not tied to any theory b/c we just don't have enough information imo jmo - is that BK had found ways to be a DD driver that involved the IDs of others - maybe just names with his pics? I cannot share links re what I've found about the potential security upgrades at DD, but they seem significant and the timing is right, so jmo imo there may be a clue there. This theory would give PC to get all the drivers' names, cars, pics, etc. and would explain the timing. as part of this, I think that the PCA was vaguely worded about DM not saying she recognized the driver.
By 12.6, the date of the DD warrants, LE had BK in their sites, and it's quite possible (likely even? idk?) that they showed DM the photo of BK and she recognized him as their erstwhile DD driver. And bingo... LE has some PC to get that info. As I said, this is only one working theory, ICBW totally, but it makes sense of the scope of the warrants, the requested info, and the timing (pre-arrest of BK, no PC for him yet so thy couldn't get his info.) Of course, another working theory is that someone(s) re DD are the CI that seems to exist imo jmo. edited to fix an annoying typo while probably still missing others
