The original YouTube video has been pulled, this is a news story:
Apparently the video was on the account of YouTube user "lildre502" who posted this equally police hating video with no guns, and the somewhat pitiful plea "plese dont get mad at me and dont send me any bad comments my dad is makeing me do this ," suggesting that the writer has been "left behind" by the educational system—the video features strong language:

If anyone can positively identify it, please let me know.
