This was absolutely a political hit - possibly a trial balloon of sorts to see if they could subvert justice by enforcing social policy post facto.
And they succeeded and then proceeded to go after others - INCLUDING Kavanaugh and realize Cosby was convicted on far less evidence than they had manufactured in Kavanaugh and were it not for his profile (and success) you can bet a Democrat DA would’ve gone after him.
Cosby got found out—Karma will get ya bad. Others await their turn at the karma wheel—they will be gotten and disgraced. My bet is that Obama will be exposed as will Nancy P. and Hillary and Bill Clinton.
