It just means they were completely transparent with the court when getting the data, and believed themselves it was lawful.
What’s hard to believe about that? They clearly put some effort into minimising the collateral privacy intrusions.
If the cops believe hard enough anything is legal.
In retrospect, the part I quoted is very unclear for what I intended. I should have added more.
What's hard to believe is the data is apparently still allowed in the case. Like... how?
"Sorry we broke the law, but its ok this one time because it would be detrimental to the case".
I mean... slippery slope? Just because they were sincere about it doesnt make it magically ok to use the illegal evidence.
