The point of the tweet is that allegations about the CIA's actions are treated as either "ummm conspiracy much?" (even if there is firm evidence of that activity) until they become "yeah they did that but it's irrelevant because it happened too long ago" even if they publish their own internal files about it. Meaning that they can NEVER be held accountable for anything.
Below are some tweets which provide further context - also these are good sources to follow imo
Hitting legs tomorrow and wondered what you guys did for legs.
1) dynamic stretching
2) calf raises (3x20)
3) back squats (4x12)
4) Walking Lunges - pass kettlebell between legs(3x45)
5) Static stretching
Evening walk - 30 minutes
I like to keep my workouts simple and relatively short.
