"I'm totally a thousand percent sorry for this, and that's not just saying this because I'm caught," Christopher Cayce told Eyewitness News in an exclusive interview Friday.

Since last summer, Christopher Cayce has been filming himself driving around southwest Houston and Midtown, ambushing people with water guns.
He was arrested Thursday and charged with two counts of assault for spraying two men on June 4.
Many of his targets appeared to be homeless, and police said some of his victims were disabled.
"Why target some of the city's most vulnerable?" Eyewitness News asked Cayce.
"In my videos, I don't just shoot homeless people," he replied.
In one video, he lures a woman to his car with money before spraying her in the face.
In another, he throws food at a man before blasting him with the water gun.
"I just put this in front of the door," Cayce said, brandishing a cross. "I walk and pray every day. Every time I go out, I pray before I go and shoot these people because I really don't want to hurt nobody."
Cayce insists his water guns were set to the lowest possible setting.
He directed Eyewitness News to his YouTube channel, where he can be seen feeding the homeless with his daughter in a video posted five months ago.
"I feed these people," Cayce said. "I gave these people $500 worth of clothes. I don't post all my positive stuff 'cause it don't get views. My channel algorithm was me shooting people with water guns."
Yet in one post, he refers to his targets as "zombies," which he conceded could come across as dehumanizing.
"I'm not calling them zombies because that's what they are. It's all commentary for the content. It's not what I really truly mean. I love everybody genuinely."
Cayce is set to appear in court on July 9. In the meantime, he said he's done with his water gun drive-bys.
"They took all my water guns," he said. "You can go buy more easily, but I told them I'm done with it. I'm not gonna shoot nobody no more."
