Behold: Graffiti artists with an apparent, albeit spotty, grasp of ethics.

An Indy reader sent us this photo, taken at Chapel Hill High School earlier this month. It appears to be a prank trolling Principal Sulura Jackson, who was accused by teachers last year of failing to cite her sources in numerous letters and writings.

Although itโ€™s cut off in the photo, the pranksters wrote โ€œcite thisโ€ before directing Jackson to Easybib, a free, online bibliography generator. They also took the time to misspell Jacksonโ€™s first name and write the word โ€œplagiarismโ€ with a slash through it.

Tensions are high at Chapel Hill High these days, following the plagiarism allegations and a recently-released teacher survey panning school leadership.
