You cannot use rifles and organized groups, as we did in the 1700's. Then, it was our rifles against theirs. Now, it is our rifles against their tanks, mortars, APCs, attack helicopters, surveillance satellites and drones, and so on.

Further, if you leave your phone at home and get to an event by travelling using cash only, you are likely safe.
