Venezuela has had US antagonistic covert ops operating in country since at least 2007. That's almost 2 decades of needing to find the US spies and their allies to prevent sabotage, coups, false flags, etc.

That's just the military aspect. They've also been under worsening sanctions for almost as long, which has been driven by the US strategy to starve the masses so that they revolt. This processes causes increased desperation among the people, which increases crime rates.

All of these things require the use of authority and as they get worse require more invasive and obvious uses of authority. It's hard enough to find spies, it's even harder to find spies and neutaize them without ripping the US off as to how you're finding them, going even further and finding spies without ever being wrong is nigh impossible.
