I cannot stress this enough. Keep your phones charged anytime you go in public. Carry a portable charger.
Familiarize yourself with the “live feature” on your apps. Learn the online handles of your local news agencies.
But please don’t flood them with nonsense. Keep this in your back pocket for emergencies only.
If you go live, explain exactly where you are and exactly what is happening currently and in the moments before. Stay calm. Facts only. Say it over and over as more viewers tune in.
