|A suspicious device worthy of calling in the bomb squad.|
Disruption Tactics - PsyOps
Simple. Nothing elaborate or expensive required.
Effective. Wastes resources, man hours, and overloads the system.
Case in point here, here, here, here, here. and so on.
If multiple simultaneous 'disruptions' occurred in strategically placed locations, to minimize the impact on fellow citizens, one could surmise that the system could conceivably become overloaded, and hence, rendered ineffective for a time being.
One could also surmise that this would be a great PsyOp operation.
To what end?
I dunno. Just something to think about when making your contingency plans.
Sometimes I find myself speculating out loud.
