I thought the flash was pretty decent.
There are many things you must consider though. Like okay there's a drug bust, but a sniper shoots yet there is no gun in the guys hand. Police snipers have no juristriction shooting unless the convict is causing harm to another person. Unless there is another gang member lets say is after him. Then this plot makes totally no sense. I hope you consider that for your sequal. If you make one that is. In my point of view you just wanted to show a good sniper scene and didn't consider the plot that much. Next time write the story on paper and you'll see how much better you can do.
