Gavin Grey: UK Correspondent on the teenage killer at the Taylor Swift dance event now facing a terrorism charge

The UK teenager accused of killing three young girls at a children's dance event will appear in court tomorrow, now on a terrorism charge.  England's Merseyside Police yesterday announced they'd discovered a bio-toxin and al Qaeda documents in the 18 year old's home following the July mass-stabbing.  UK Correspondent Gavin Grey told Ryan Bridge it's a shock twist in the devastating case.  He says despite the terror charge, counter-terrorism Police say the incident isn't classified a terrorist incident.  LISTEN ABOVE See omnystudio.com/listener for privacy information.
