What the hell is a butt bump？ Survivors of the shooting in Las Vegas in the United States angered the three parties involved.

　　　　　　 CCTV News:The shooting in Las Vegas, USA is still under investigation. Recently, a 21-year-old survivor of the shooting case filed a lawsuit in court, bringing the MGM International Hotel Group, the organizer of the open-air country music festival and the manufacturer of the butt joint to court. On the 11th, the Oakland County Court in Nevada accepted the case.

　　　　　　 The name of the survivor who filed a lawsuit is Gasper. In the shooting incident on the 1st, Gasper was shot in the right side of his body, causing his ribs to be injured and his liver torn. He is now recuperating at home.

　　　　　　 Gasper’s lawyer said at the press conference that the hotel Mandalay Bay Hotel failed to effectively monitor the hotel guests, and several guns and 10 suitcases brought into the hotel by the gunman paddock were not found. At the same time, the lawsuit claimed that the hotel staff did not respond quickly enough to the shooting, the organizers of the music festival failed to effectively maintain the safety of the concert, did not properly mark the emergency exits, and did not train employees to deal with emergencies.

FBI investigators sealed off the scene and continued to investigate the Las Vegas shooting.

　　　　　　 Gasper’s mother said that their move was not to ask for compensation, but to urge the organizers of large-scale activities to be vigilant and protect the personal safety of the participants.

　　　　　　 At present, the defendant’s three parties have not responded to this.

　　　　　　 Just before that, an American non-governmental organization advocating the control of firearms filed a class action lawsuit with the court on behalf of three audience members at the crime scene, demanding punitive damages from a group of manufacturers and sellers of butt butts, such as "Collision Scheme" company.

　　　　　　 At present, the sale of fully automatic firearms is strictly restricted in the United States, and the buttstock is an accessory of firearms, which can improve the shooting speed of semi-automatic firearms and achieve the shooting effect of fully automatic firearms. The gunman paddock committed a crime by using the buttstock, causing heavy casualties.

The staff of a gun shop demonstrated the working principle of "buttock".

　　　　　　 [Extension] The motive of the gunman who wanted to create a greater disaster in the shooting in Las Vegas is still unclear.

　　　　　　 According to comprehensive reports, many days after the shooting in Las Vegas, the police launched an investigation into more than 1,000 clues provided by the public, but they still lack a clue about the gunman’s motive. The investigation also found that the gunman had shot at a nearby aircraft fuel depot with the intention of creating a greater disaster.

　　　　　　 Mike Maher, a police officer in Clark County, where Las Vegas is located, said that investigators still have many mysteries about this case. They don’t understand why paddock, a wealthy retiree, was desperate to commit such a cruel massacre. Police said that paddock did not leave a suicide note, record or send out any information on social media that might reveal his motives.

Two dark broken windows on the resplendent exterior wall of Mandalay Bay Hotel in Las Vegas, USA, are shocking.

　　　　　　 McMaher said: "We searched everything, including the suspect’s private life, political orientation, social behavior, economic situation and any potential for extremism … … Traced any clues of the suspect from birth to death. "

　　　　　　 The authorities have previously appealed to the public, including erecting billboards around Las Vegas, hoping that someone can provide any information that can solve the mystery of the case.

　　　　　　 He said that although the "Islamic State" organization claimed responsibility for the shooting, the investigation so far has not found any relationship between the Islamic State organization and paddock. McMaher also ruled out the possibility that paddock had an accomplice. He said that the investigation confirmed that there was no one else in paddock’s room on the day of the crime.
