Police said the incident stemmed from a dispute in a park near the house of Glen Nicodemus, 59, of Rochester. Steven Clancey, the chief of police with the Rochester Police Department, told ABC News Nicodemus was having trouble with a group of kids who had been allegedly harassing his mother.
Nicodemus then spotted the kids he thought were involved and went to the park to take their pictures so he could identify them to police, Clancey said, though he noted he did not know if it was actually the group that was allegedly making fun of Nicodemus' mother.
The group of kids and Nicodemus got in a "dispute" at the park after he began taking pictures of them. Police responded to that incident and spoke to all involved before everyone parted ways without arrests or citations.
It was about half an hour after that when some of the kids, including 14-year-old Jaiden Rodriguez, walked by Nicodemus' home, saw he was outside and began exchanging words again, according to Clancey.
In the video of the Aug. 14 incident apparently taken by one of the kids, Nicodemus can be seen grabbing his hose and spraying Rodriguez after telling him he was "a member of the Ku Klux Klan." Rodriguez makes threats to beat Clancey up, but walks away with friends as he's being sprayed.
Christina Poles, Rodriguez's mother who later posted the video to Facebook, said Nicodemus provoked her son and the girls he was with as they walked by.
"[My son] didn't just go to his house and start messing with him," Poles said.
She added that Nicodemus sprayed Rodriguez once before the video started recording.
While Rodriguez has since been nervous about going to police and "advocating for himself," Poles said, the support from others has made it easier.
A man who identified himself as Nicodemus' father declined to comment when reached by ABC News on the phone.
Police said the incident did not rise to the level of a hate crime after checking with the New York State Police Hate Crimes Unit and the Monroe County District Attorney's Office.
Clancey said a judge did issue an order of protection for Rodriguez, but noted that Nicodemus is not a member of the KKK.
"[Nicodemus] said some stupid things … but there's no hate crime here. Just harassment," Clancey said.
Nicodemus was arraigned by police on Wednesday. He has since been released and will report to pre-trial release under supervision.
Poles called his charge a sham, saying she feels the police aren't taking it seriously.
"The charges that he got charged with, I get more for jay-walking," she said. "It's like the laxest punishment I've ever seen."
