Not surprising that its an islamist extremist. First thing I thought when the news broke. Innocent civilians dont deserve to be targeted like that.
Its funny how this will straight away bring up about America's gun laws when there is no doubt a high possibility these weapons were not purchased legally. Guns being legal/illegal has no bearing on any terrorist attacks, the illegality of firearms hasn't stopped the attacks which happened over Europe.
RIP to those killed and to the ones injured, hopefully you will all make it through this.
