I have worked in campaigns before and a lapse like that - just 4 times where donations exceeded $10,000 is actually very good in relation to the perhaps 99% of donations that followed the basic Green principle. Weaver could not have been aware of these donations because only financial agents know when this has occurred within a riding. The key issue was whether this was a common practice among the Green campaigns and obviously it was not .  Thus, it is just cherry picking a tiny number of lapses, insignificant when compared to the big donations of the Liberals and NDP and very common in campaigns where enthusiastic volunteers often unknowingly violate campaign rules or party policy
