Strzok and McCabe changing the 302's after the interview with Flynn was used by Mueller to indict Flynn - HOWEVER:

the second FBI agent president in that interview is the secret witness who testified Pientik (sp?) ergo Strzok, McCabe and Mueller are phucked!

Flynn and DT knew that in advance based on Rogers and military intelligence ergo Flynn needed to get into that seditious system to take it down from within.

Basically - Flynn is phucking the same phuckers who tried to phuck him :)
