The two men had never spoken, White said, but he always sees Blake's kids playing outside.
White saw Blake and his children again on Sunday, when he recorded
Blake being shot multiple times by police while his three children were in a car.
Blake is in stable condition in an intensive care unit, according to attorney Ben Crump, who represents the family.
The video -- which drew more than 2.4 million views from Crump's Twitter feed alone -- has since sparked outrage in Kenosha, a city of 100,000 located on the Lake Michigan coastline between Chicago and Milwaukee.
"It's disturbing to actually look out the window where I live and see this man get shot by the police seven times," White told CNN on Monday. "It's highly disturbing to me, but I'm pretty sure Jacob's kids were more traumatized than anybody during the whole situation."
Blake's shooting comes as protesters across the US continue to call for justice in the ever-growing list of Black people being killed by police, including the encounters that killed
George Floyd and
Breonna Taylor. Most recently, protests erupted in Lafayette, Louisiana, on Saturday after
police killed Trayford Pellerin, 31, a Black man, outside a convenience store.
White said he hopes the officer who shot Blake takes responsibility and confesses to using excessive force or apologizes for the shooting.
"I really hope everybody sees what's constantly going on around the world and this country," White said. "I hope they actually get justice for this man."
What White saw
Kenosha officers were called to a domestic incident about 5:11 p.m. Sunday, police said. The shooting unfolded on a residential street packed with apartment buildings.
White says he saw Blake get of a his truck and approach his son, who was on the lawn. Blake told his son to get into the truck while Blake walked into the apartment building behind a woman who was outside.
After stepping away and coming back, White said the scene drastically changed. Police were wrestling with Blake.
"One of them had him in a headlock and was punching him in his ribs, the other had him in a headlock on the other side of him and was pulling his arm," White told CNN.
"After they punched him in his rib, the female officer Tased him and Jacob kind of leaned on the car and they proceeded to wrestle him toward the back of the car and he went to the other side of the car. When they were on the other side of the car on the ground, I had to pick up my camera and start recording."
That's where the video starts. The clip shows a Black man walking around the front of a gray SUV with two officers a step or two behind him, one with his weapon trained on the man's back. As the Black man enters the driver side door of his car, the nearest officer grabs the tail of his tank top and seven shots are heard.
The man entering the car appears to go limp. A sustained car horn blares. A woman nearby jumps up and down, apparently in anguish.
"The officer that shot him, he got on his knees," White told CNN. "He was trying to help him. He put his blue gloves on. Backup came. The other officers tried to help him."
White said he was angry and traumatized by what he recorded, adding that he was unable to sleep Sunday.
"The police want everybody to know they're out here to protect and serve, but you guys are constantly giving us -- Black people, in particular -- reasons not to let you guys protect and serve," White said. "We don't want you guys around because we are scared for our lives. You come to an incident to disarm an argument, and this Black man gets shot. It wasn't supposed to go down that."
