Finally tonight, we return to Buffalo. Ten people lost their lives there this weekend. We wanted to take a moment to reflect on how they lived their lives and the legacies they leave. Katherine Massey was known for her advocacy. Last year, when a family member of a state lawmaker was fatally shot, the 72-year-old wrote a letter to The Buffalo News calling for stricter gun control measures. A friend told reporters she would fight for anybody, without a doubt. Fifty-five-year old Aaron Salter was a Buffalo police officer for three decades. After retiring in 2018, he took up work as a security guard at Tops Friendly Market. Salter fired back at the shooter, and is credited with saving lives. President Biden spoke yesterday about Salter's heroism: We pay tribute to all law enforcement officers and their families who understand what it takes, what's at risk to save and protect all of us.
