That was not what Kimmel said. Kimmel continued the gaslighting and tried to paint the killer as a right winger, said the right wing was "desperately trying to claim it wasn't one of them"... He surrounds himself with an echo chamber so deep he didn't even know that there was more information, that the kid was no right winger, though his family is, and lived with his trans woman lover, which provided his motive. Instead Kimmel gaslit his audience.
ABC cancelled him because affiliates were dropping the show. Instead of any number of options the corporation chose to burn the fields and salt the earth. If you are upset that he was cancelled, you need to talk to ABC. Tell them to have some balls maybe, act in your interest. Get them to understand that their best interest lies with pleasing Jarod rather than telling the truth.
