The following is a copy of the Tweets sent by Dallas police Major Max Geron during the attack on the Dallas police headquarters. The attack started this morning, around 1230 AM.
The tweets illustrate how public officials can use social media (in this case Twitter and Periscope) during an incident to keep people informed, correct errors, quash rumors, explain actions, keep people safe, and help make sense out of what’s going on.
Max writes for Homeland Security Watch sometimes.
