WHITE PURPETRATOR ENABLES GUN CONTROL DISCUSSION
Las Vegas - The purpetrator of the Las Vegas mass murder was white and American, which cleared the way for a debate about gun control today. "I said on Facebook that those Americans really should do something about their guns", a Dutch man said. "If the purpetrator was muslim or African-American, the entire debate would be about terrorism and racism and stuff like that. I'm not touching those subjects."
