What Inspired the Helicopter Attack in Caracas?

The day after an apparently rogue police helicopter flew over government buildings, dropping hand grenades on the Supreme Court, theories abound about what the incident means for Venezuela's future. It is clear that the attack was not part of a coordinated effort, but it could have been intended to spur broader action by the armed forces and by the dissatisfied Venezuelan public. Therefore, it should be judged not by its short-term ineffectiveness, but by its place in the broader crisis.
