Transcript for Investigation into deadly New Zealand terror attack
Want to bring in Pierre Thomas and he was hitting on something so important. What we've seen in recent months in recent years, a rise in white supremacism and right wing violence. Reporter: That's right, George. The early evidence suggests the killer in New Zealand was motivated by hate so there is cause for concern in the U.S. As well. According to the FBI the number of hate crimes has jumped a dramatic 17% when comparing 2016 to 2017. There were more than 8,000 victims in 2017 and, George, sadly, 58% were motivated by race, 22% were motivate the by religion and this chilling reminder, the New Zealand suspect was allegedly inspired by anders revic and we had a coast guard lieutenant accused and he studied breivik as well. So many attacks on places of worship. Reporter: We have, George. You know, we just had the incident in Pittsburgh a few months ago, all those people this is an ongoing concern and given the scale of the attack that we saw New Zealand we're seeing law enforcement officials in Los Angeles, San Francisco and New York providing extra patrols today. We're seeing that at the islamic center in New York. Pierre Thomas, thanks very much.
