No, your Facebook check-in at Standing Rock won't confuse police targeting Dakota pipeline protesters

We contacted the department about the rumor, and an officer explained not only that they were not using Facebook check-ins as a gauge of anything, but that the metric presented no intelligence value to them. The rumor suggested that protesters cited Facebook check-ins as a manner in which police could target them, but check-ins were voluntary — and if police were using geolocation tools based on mobile devices, remote check-ins would not confuse or overwhelm them.We also contacted Sacred Stone Camp to determine whether they were the source of the social media plea. A representative clarified the rumor, telling us that police do sift through social media for "incriminating material" (not whether or not they were at the site, however) and to generally monitor the protests. They told us that the group appreciated the gesture of solidarity, but that the message did not originate with their camp. [Snopes]
