I do not know enough about this man to really determine whether or not appointing him Commissioner is a good move. I know he was national security advisor for both Mulroney and Martin, but that's about it.
I did read this though: (it's from a statement issued by Sue Barnes, Lib Public Safety critic)
Newly-appointed RCMP Commissioner William Elliott was the senior public servant who met with Mr. Zaccardelli between his two conflicting appearances before the Public Safety Committee in the fallout from Justice O'Connor's report on the Arar affair. Canadians are still waiting for answers about when the government became aware that Mr. Zaccardelli had misled Canadians and what steps have been taken to evaluate which version of his testimony was the truth.
"Mr. Elliott's involvement in Zaccardelli's testimony and his past experience as a political insider will raise some doubts among Canadians about the legitimacy and impartiality of the overhaul of the RCMP management culture at a time when the credentials of the Commissioner must be unquestionable," said Ms. Barnes.
She's also calling on the government for him to appear before the Public Safety Committee, before he's appointed. Good luck with that!
All the same, I will wait to see who this man is before passing judgement.
