Pam immediately shot up to attention as a lone figure stood high on the balcony. Who the hell did this creep think he was? However, the dead police officer's body was all she needed to see to know that this guy was a threat. He spoke of meta-humanity as if the lot of them were anything more then human. What arrogance. However, she'd deal with his negative attitude after she dealt with the ball of light growing in his grasp. This could not end well, and as he moved his arm to throw the projectile Pam had leaped off her seat and into action. 

If she had time to think she would have thought she was insane, followed by thinking about how dead she was. But fortunately the military has ways of disabling that line of thinking.

Pam dashed across to make an interception with the light missile, desperate to protect the crowds. She leaned back and let the wheels carry her and the missile came into range of her powers just inches above her hands. She spun the spear of light as quickly as she could for two seconds before letting go and redirecting the directory of the missile towards the entrance of the facility, away from the main body of the crowd. The force of the explosion threw Pam off of her feet and she flew until she collided painfully into a nearby wall. She placed her feet underneath herself and landed with as much grace as she could given the circumstances. It was a really good thing she was wearing a helmet. Pam picked herself up with a groan in order to inspect the damage dealt. 

Despite her best efforts.. it wasn't pretty. The entrance was half caved in and there was a large charred hole in the ground left behind by the meta's explosive powers. While the explosion didn't land inside of the crowd, it struck them with the force, and it was clear by the pile of writhing and harmed people that there could be casualties and many broken bones. Pam might have saved a few lives with her crazy stunt, but whoever did this was running rampant in the upper levels of this place. She had to move! Pam could feel eyes staring at her as she leaped for a flag pole jutting vertically out of the nearest wall. She didn't know what they thought; did they think of her as a hero for trying to protect them against the explosion? Or did they see her as a filthy meta human, no better then the man who made and attempt upon their lives? She pushed the thoughts to the back of her mind, knowing that doing the right thing was important no matter what people thought of you. But it didn't help her fight back the feeling of shame.

Pam used her powers to spin herself around the pole like a gymnastic. Spinning spinning spinning.. gaining more and more speed. To the crowd below if she hadn't already revealed her meta-human origins it was now plainly obvious. She spun until she had gained enough speed and let go, flinging herself up towards the balcony where the mad man had been previously standing and managed to grab the ledge. With some effort she hoisted herself up and was met with the kind of carnage she hadn't seen since she was in service. Several police officers were sprawled on the ground, with pools of blood gathering everywhere. Limp bodies of police officers were strewn everywhere. This guy seemed like a tough guy, whoever the hell he was. It was then she noticed that one of the officers was still alive. Pam knelt by his side and inspected the wounds like she had been trained.

It wasn't good. If this guy got into a hospital immediately he would have a chance of survival, but the ambulances would be too occupied with the crowds below and he was all the way up here. And unfortunately she didn't have the time to lug him to the hospital herself. It was a tough decision but.. she did what she would have expected her fellow brothers and sisters in arms would do for her. 
"I apologize for what I'm about to do," she said as tears reached her eyes, "You will be remembered fighting to protect what you loved." And with that, she used the gun he had in his holster to quickly put a bullet through his head and to end his suffering. She quickly equipped the man's gun and ammo before making her way inside with determination in her step. This guy would pay for what he had done to the innocent people here today, she would make sure of that.
