Police "not entitled to use unlimited force to affect an arrest"

Numerous news reports today are quoting a court decision "A police officer is not entitled to use unlimited force to affect an arrest"; e.g., The Globe and Mail (below), Global News, and CTV News.  (The Star's story doesn't carry the quotation, but I don't have separate blogs for calling out other news sites!)

I haven't seen the decision yet but I'm assuming that this is a direct quotation.  In any case, I'm pretty sure the correct word here is "effect" (see http://public.wsu.edu/~brians/errors/affect.html).

Interestingly, CBC News quotes the word "effect".  Did they quote it inaccurately?  Or is it OK to fix an obvious error in the source being quoted?  Or should the other news outlets have used [sic] to exculpate themselves from the mistake (and embarrass Madam Justice Louise Botham)?
