The cops covered Jerlina immediately. The shooter was restrained by the other cops and a commotion ensued. He was still cussing at her saying that she doesn't deserve to live and stuff like that. Maybe because she's gotten used to such situations already, or maybe because she was sure that this is staged, she didn't feel scared.
Also, her mind was entirely occupied with Jeremy. And she wanted to get inside and so when the cops led her inside, she happily went inside. The police used this as a chance to start controlling the crowd and even the media were asked to step back as it is not safe anymore for them.
"There could be more of them," they said and started to disperse the crowd. "It's for your safety!" "Disperse!"
