 police in New York is using vehicle mounted projectile launches to fire GPS trackers embedded in foam darts with sticky glue in them. The idea is to reduce the need for a dangerous high speed chase. When there's a high speed chase, you have two cars that can run into folks and kill them. If you hit them with a GPS tracker, you have no high speed chase. Because there's no one chasing the suspect, you're just tracking them. So that's much safer for everybody. The ACLU has weighed in on this and said, if someone is a valid suspect, right, which is usually what happens with a high speed car chase, the police saw them commit the crime or have have credible evidence that they committed the crime and they chase after them. In those cases where you could chase after them, it's fair to track them until you've apprehended them. And as long as you don't continue to track them after the apprehension or after the case, as long as you're not using it to continue to track them, the ACLU of all people is fine with this.
