    According to the tweet, the encounter began with "a traffic stop for unlawful speed." If so, then the initial stop was legitimate, but in and of itself that wouldn't be probable cause to search the car. It does give an officer the right to look inside, and if contraband is in plain view, that would be probable cause. Here we don't know whether the bag full of drugs marked "BAG FULL OF DRUGS" was laying out in plain view, but it seems entirely possible.
