(Obviously) the Buffalo shooting. I lived about 2 hours away from the city at the time, so I was not directly affected in any way, but I remember seeing only discussions about Payton Gendron and the actions New York state would take to prevent future shootings on the news for a very long time. A local Tops market I frequented then had also built a little memorial for the victims out front, I assume other ones in the state did the same as well.
