NBC新闻:美警方逮捕被控制造恐怖威胁女子

In southeastern Oklahoma eighteen-year-old Alexis Wilson is charged tonight with making a terrorist threat. Accused of telling a co-worker, she wanted to shoot up McAllister high school which she once attended. Court documents say she recently bought an Ak-47 assault rifle and said she was going to "shoot 400 people for fun". She later said she didn't mean it but the County Sheriff is taking no chances with people who threaten schools. We're gonna charge when the district attorney's gonna prosecute her to the fullest effect. I mean it's... This is something we can have zero tolerance over. 

In Desert Hot Springs, California, three 14-year olds, two boys and a girl are charged with threatening on social media to shoot their high school. Police say the teens had access to a semi-automatic pistol and a revolver as well as this pellet gun that looked exactly like an Ar-15 assault rifle. If they had brought it to school police say it could have been easily mistaken for the real thing. Our officers would have no way to make that discernment within a quick second and it could have ended in a very very different manner. Tonight officials are praising the people who took both threats seriously and tipped off the police in this era of mass shootings.
