The person who placed a suspicious package at the University of Oklahoma won't face charges. | MORE | OU gives all-clear after bomb squad investigates suspicious package OU's Norman campus saw a massive police response when someone put a sign and package on a lawn outside Gaylord Hall. The OU Police Department said the person who placed the package on the campus came forward, but they are protected by free speech. The package even led to a response from a bomb squad robot. In an audio recording by the campus' student newspaper, OU Daily, OU police Chief Nate Tarver said the university Staff Senate that officers were suspicious of the package, and they chose to use caution. "Sometimes, we don't know what it is. So based on that, we have to approach it from that point of view and make sure that it's not something that's going to be detrimental to all of us," Tarver said. When the sign and package were left, it wasn't known who put them there. "As luck would turn out, someone actually did contact us and let us know that they put that there, but there was no malicious intent. It was protest art," Tarver said. The protest art was about the war in Gaza, where thousands of people have died. The Student Coalition for Palestinian Liberation said in an Instagram post that they weren't involved, but that this shines a light on the Palestinian side of the war. While the police chief ruled out criminal charges, the university said they are reviewing the situation and could address it through "university processes."
