On Tuesday, a Venezuelan official flew a helicopter to his nation’s Supreme Court. On arrival, he dropped grenades onto the building. He then released a video identifying himself as a police officer named Oscar Perez. Standing in front of masked men, Perez called on the Venezuelan people to resist the country’s president, Nicolas Maduro.

While no one was injured or killed, this is a significant incident. It speaks to the growing disenchantment of security forces within President Maduro’s regime.
