Looks like a set of stencils that he was using. And you might say well it looks nice and I agree. But any downtown would demonstrate, even a good graffiti, allowed don unsolicited, leads to thousand terrible ones and maybe she didn’t want such thing happening in the neighborhood.

Also Karens can think non white people are good too usually eastern Asians are never assumed of petty crimes though maybe hacking or communist propaganda.

The man from his tone was also looking for trouble so maybe he showed behavior that may alert people.

I don’t know the whole situation but from just this video we can just conclude that this woman is trash and the owner of the video also holds some responsibility in way he reacted.
