Here is probably the best description of what is really going on. I saw it on Newsmax, but Dershowitz is not a fan of Trump.
"
The constant attempt by leftist prosecutors to get former President  Trump shows that we're past "losing our minds, we're losing our rule of  law here," Harvard Law professor Alan Dershowitz told 
Newsmax on Monday.
  Dershowitz continued by telling a story about his time as a civil  rights monitor in the South in the early 1960s. He and the rest of his  class were taught by the demonstrators not to spit on the sidewalk,  because they will turn it into a felony, such as destruction of  property, since "they're targeting every civil rights worker."
  "Is this what District Attorney [Alvin] Bragg wants to emulate? The  South in the segregation period, where they were "getting" civil rights  workers?" Dershowitz asked 
"Rob Schmitt Tonight." "Because that's what this is like."
