You claim that the Walkerton deaths were the responsibility ENTIRELY of the Koebel brothers and the local utility. 

You are wrong.  

Mr. Justice O'Connor laid the fault on them AND the Harris government. Here are two more excerpts from his Report:

1. "The provincial government’s budget reductions led to the discontinuation of government laboratory testing services for municipalities in 1996. In implementing this decision, the government should have enacted a regulation mandating that testing laboratories immediately and directly notify both the MOE and the Medical Officer of Health of adverse results." 

2. "The provincial government’s budget reductions made it less likely that the MOE would have identified both the need for continuous monitors at Well 5 and the improper operating practices of the Walkerton PUC."
