I do not support having my cell phone location data sucked up by the government in general while exercising my First Amendment right to protest. That this particular government is doing it is frankly, terrifying.

This particular article was about using Stringray with a warrant. I'm sure that the government is abusing Stingray but it'd be nice to have evidence first.
