This ruling was not specific to the use of stingray devices, those are still legal to use if they have the proper warrant. What's illegal with stingrays is lying about where the information came from on the warrant or in a trail. No surprise lying to a court will get you in trouble.
This ruling absolutely will have an impact on the relatively widespread use of those little memory dumping devices that cops love to use in routine arrests and even traffic stops in some states.
Just exactly why you believe it will make any dent? With Holter behind steers, why would you think anyone will require any sort of legality or transparity from anyone that works for Government??
