From your source:
"In mid-August last year, he had begun working as a lifeguard at the Pleasant Prairie RecPlex in Kenosha County and — although he did not possess a driver’s license — would drive to work from Antioch each day, he said. Rittenhouse told the court that he drove to work on Aug. 24 and stayed in Kenosha overnight at Black’s stepfather’s house. He remained in the city on Aug. 25, cleaning graffiti off a high school early in the day and then later going to a local store to buy a sling for his rifle."
He was working in Kenosha, and how dare he clean up graffiti!!!
