On 28 October Director Comey wrote to congressmen to inform them of the Weiner computer seizure.
On 30 October the FBI got its warrant to begin examining the contents.
It's 6 November in the US - that's 7 days that Comey's had to examine 650,000 exhibits.
To get the job done in 7 days working 24 hours a day without breaks and spending one minute assessing each of those exhibits would require 77 people - now multiply that by 3 x 8 hour shifts per day - that's around 210 seasoned detectives conjured from nowhere, dropping everything else and doing nothing but reading.
