Query: Corruption substantiated

Excellent expose on the Mulroney administration. What we all suspected has been extremely well researched and summarised. It's a national embarrassment that this man due to his legal and political connections is untouchable. This book should be compulsory reading for any Canadian history student so that Canada does not, through inept choice of leaders, repeat the mistakes of the past.
