It's just like our border. We don't really "apprehend" anyone. We give them a food voucher and a bus ticket to parts unknown USA.
In fact, laws are only for little, powerless people. You are more likely to be arrested for an unpaid parking ticket than for treasonous secret negotiations with terrorist countries.
Times have changed. With POTUS in charge, if he went after Kerry and others from day 1, the Dems would pose it as partisan and “too many” members of the public would agree. All of Obama’s servants were treasonous and they are being investigated, and now it’s dripping into the public sphere to prepare the public for prosecuting these traitors.
I’ve been reading the DOJ website and I’ve seen lower level criminals from OBama’s regime being sentenced for crimes they were charged with a year or more ago. So timing wise, investigations on those criminals started soon after POTUS took office.
There are so many hearing transcripts being released, grand juries empaneled - this is all different from Obama’s era. Times have changed and the criminals are taking to the airwaves lying. An acquaintance of mine doesn’t follow the news and would adopt whatever political stance was popular in her circle. She said, “All I know is everyone is saying Trump is lying, a liar, lying some more and on top of that lying.” The public isn’t quite ready to accept the reality of who the real criminals are - it takes exposure.
The underlying issue resulting in General Flynn’s case was an allegation that he could have been violating the Logan Act. Only Republicans have suffered from an investigation into a purported violation. Actual violations by Democrats have been ignored for decades.
