Insurrection is not war. Insurrection is a violent uprising against a government, which is exactly what happened. The fact that explosive devices were not used, but were present, was likely a matter of luck, not intent. Besides these things are not required for something to be an insurrection. They could have been armed with screwdrivers and hammers and it would still be an insurrection, albeit a less extreme insurrection.
