The Flag in the video!

Can anyone tell me where i can get one of them flags? i seen one with rapper immortal technique a few years ago. i've been trying to find one forever! if anyone can help me this would be very appreciated. as well,i think this song is dope but i don't think the video is very appropriate . that is a way serious issue to some.i think he could have done another theme. i understand it is hype for the new album. What do you think?
