Here's an article: http://www.cnn.com/2008/US/11/28/black.friday.violence/ 
And this is the specific part[s] I have a question about:
[=Verdana, Arial]"Several minutes" passed before others were able to clear space around the man and render some aid. Police arrived, and "as they were giving first aid, those police officers were also jostled and pushed," he said.
Asked about the possibility of criminal charges in the Wal-Mart death, Fleming said he would not rule it out but noted that charges would be "very difficult," as it would be "almost impossible" to identify people in the crowd from the video and that those in the front of the crowd were also pushed by those behind them. Hundreds of people probably lined up in an orderly fashion, he said, but got caught up in the rush.
Alright. They cannot identify/apprehend the absolute scum of this Earth that murdered Walmart guy[=Verdana, Arial]®. Understandable. What about those that "pushed" and "jostled" police officers? Now, I am very certain that people can be arrested and hauled away to jail for simple TOUCHING a police officer, police horse on duty, et cetera, and in cases of accidently bumping into a horse, or the horse bumping into you, I am against such ridiculous detainments. But if there was ever a case to detain and book every single piece of human scum within inches of the police uniform is this not it? I'm delving into hyperbole here of course. They could have arrested those that pushed them, right? I mean. They SHOULD have arrested those that pushed them. Next year, if they're closer to the door[s], those same people [that pushed officers to save 50$ on some NEEDLESS manure] are going to be the murderers of next [/]Walmart guy[=Verdana, Arial]®. :(
