1. Sounds like a plan to encourage fence sitters to acquire firearms. If you’ve been told all your life to call the police when you need help, and your then told you won’t be able to call for help, it might encourage you to get a gun.
2. Mixed feelings:
—My understanding is that sometimes explosives are set off remotely via cell phone. Shutting down service in a limited area might be useful in such a circumstance.
—Sometimes the rioters, demonstrators, troublemakers use cell phones for their communications. Shutting down the service in a limited area might be useful sometimes.
—Shutting down the internet and cell service will affect the “good guys” as well as the “bad guys”, no matter what your definition of either of those is. Government officials, whether acting as good guy or bad guy, will be affected too. They will lose functionality with a wide area long term shutdown.
3. SP303? Is that like Rule .303?
Keep a landline. Cell phones are easier to shut down (towers, jammers)
