So basically they are holding him to the Ted Kennedy standard of proving innocence.
How does one prove he did not rape a woman? It falls on the accuser to provide positive evidence a rape was committed. Otherwise any woman can claim any man raped her.
Courts still require actual evidence other than heresay accusations that anyone can make. Without any negative consequences if they are caught lying.
Produce the blue dress. That was actual evidence. Thst was irrefutable.
