Every single American – young and old - must be given training to survive a new wave of mass shooting attacks launched by a'new breed' of killer, according to a leading active shooter survival expert. Speaking on the first anniversary of the Las Vegas Mandalay Bay shooting – which saw 58 people killed and hundreds more injured in the deadliest gun atrocity in US history – security firm boss Michael Julian said the number of people being killed in mass shootings is increasing year on year and the shooters are becoming more'sophisticated' with each attack. Julian is the creator of the ALIVE active shooter survival plan and travels across America teaching law enforcement, schools and businesses how to survive an attack. Speaking at the 93rd annual conference of the World Association of Detectives (WAD) in Las Vegas, Julian says the current situation is'critical' and it's time that everyone, even young children, receive the necessary training and education. 'Yes, in my view every man, woman and child should receive some level of training on how to handle an active shooter situation,' he told DailyMail.com.
