This is a good step forward, but until we (the citizens) are able to say that LEOs are no longer using parallel construction[0], this is a lot less helpful than it could be. This just means LEOs have to work a bit harder to mask their illegal activities.<p>For example, say you're talking to your friend who sells weed and drive over to pick it up. The cops know you're buying drugs, so they pull you over for rolling through a stop sign, search your car, and "stumble" upon the weed. There is no way to prove they used a Stringray to get this information in the first place. Extrapolate this to other activities.<p>[0] - <a href="https://en.wikipedia.org/wiki/Parallel_construction" rel="nofollow">https://en.wikipedia.org/wiki/Parallel_construction</a>
