Maybe it's the NDP that should have not responded to the CBC reports and not expelled Weir? I think Weit felt that remaining silent would have left a negative lasting impression about him with the public. Why should he remain silent after his accuser has chosen to change their position and not remain silent?There was no need to respond to the CBC report, certainly not so urgently. If he had kept his mouth shut he would have been reinstated and his career would be fine. Everyone would have accepted the plea of social awkwardness.
Because he, not "his accuser" made a deal to be reinstated to caucus which included his accepting responsibility for his actions by going to anti-harassment training. People who didn't do anything don't need anti-harassment training.
