Apparently no one took Light's very obvious foreshadowing seriously, which she took as liberty to do whatever she wanted to these gang members. this was apparent with the zeal she showed when she hit the drop zone. Though while zealous, Light wasn't stupid, and while she was dropped off, no one seemed to notice, or at least until she had left the area and gone into hiding. While her toon looks made stealth awkward, she was only going to do it for as long as she could do it for. Mostly because she didn't fancy being a bullet sponge, at least until she was at least in leaping distance. 

Hiding behind a wrecked car outside one of the buildings near the dropzone, Light snuck in through a door that was ajar. The first gangster she dealt with was around the corner looking out of the window at Bio Beast, who was doing his own thing. This gave Light a nice opportunity to knock them out, and thanks to the comotion outside, Light moved like this, knocking out various gang members through various methods, laughing a few seconds before knocking them out using various laughs from different horror things shed seen. This continued on for a couple minutes until she accidentally knocked down a wall knocking a guy out, opening up a big room with a few gangsters and a meta waiting, which took off more fire from the people outside to deal with Light.
