Let's go over some of the details.
"Our role in this review was not to second-guess discretionary judgments by Department personnel about whether to open an investigation"
1) FBI heavily abused the FISA process. Presented false info and withheld exculpatory info from the court.
2) FBI used 'defensive briefings' to investigate Trump campaign officials
3) FBI relied on knowingly dubious sources for anti-Trump information
IG identified "numerous serious factual errors and omissions in the applications ... that undercut certain allegations in the FISA applications."
They knowingly used bad information to surveil American citizens in the Trump campaign.
Wow.
Strzok said he "didn’t know whether Bruce Ohr kept meeting with Steele after Steele was terminated." But Strzok’s handwritten notes show he got updates on 12/12/16, 12/20/16, and 1/23/17 regarding Ohr and Steele's ongoing communications !
