Sounds like just another Gun Grabbing Democrat Propaganda article.   While completely ignoring "Why Islamic State would target Las Vegas Nevada" and or Claim to have demanded, Ordered,  the Attack.    Hint if you don't know start researching what is at Clark County Nevada.  This also would be part of the Muslims' 109 Suras of the 114 Suras of the Holy Koran's  Written Declared War Against Christians, Jews, Unbelievers.   As far as the other Mass Murders, involving Firearms at the U.S., the Study Demanded by President Obama done by Vice President Biden explained everything too well, "Culture of Violence",  as basically the young are being raised on the Violence of Video Games, and Violence in Movies, Media to the point that is normal acceptable behavior, the proof being the things that imitate art like all the Vehicle Mass Murders that are like Mr. Mercedes (TV Series).
