Yeah, they were 'very careful' with classified material.

Right.
At least five emails determined to be classified were found among 2,800 documents stored on a laptop belonging to Anthony Weiner, whose then-wife Huma Abedin was deputy chief of staff to then-Secretary of State Hillary Clinton. 

The State Department released hundreds of pages of materials Friday afternoon, including a total of eight pages classified at the 'confidential level,' the third most sensitive level the U.S. government uses.
Anybody other than Hillary & Staff would've been in a cell a long time ago for this crap.  And if Comey had any sense of shame he wouldn't be able to show his face in public for helping them stay out.
