WATERTOWN, Wis. Riverside Middle School in Watertown, Wisconsin, was placed on a "cautionary lock and hold" Friday during a planned student walkout protest over the Watertown school board's decision to ban a song from the high school's spring concert.In a message to parents, the school said it had been made aware "of a rumor that impacts student safety outside of the building" during the planned walkout. An announcement played at the school told students they would remain inside for the remainder of the day. "Again, at this time, this is a rumor, but we need to ensure the safety of students," the message to parents reads.Riverside said it is in contact with the Watertown Police Department and has an increased police presence at the school.Students at the middle school had planned to walk out at 10:30 a.m. Friday to protest the school board's decision to bar Watertown High School from performing "A Mother of a Revolution," an instrumental piece that honors a transgender activist involved with the Stonewall uprising in 1969.Despite the lock and hold, some students made their way outside. Allie Roberts, a student who helped organize the walkout, described what happened when students tried to leave."We forced our way through pretty much a wall of teachers."Roberts said she organized the walkout because of her connection to the issue.Watch: Middleschooler Allie Roberts talks about how the students got out despite a lock and hold Allie Roberts 2"I'm a band student myself and I know that I personally would be really upset to have spent 7 months working on a piece just to have it taken away a few days before the concert."Roberts said the high school walkout earlier in the week inspired her."That is so inspirational and that they were able to find the courage to leave the school building in order to spread awareness."Camila Sievenlise, another student who participated, said she walked out because of what the cancellation means to her fellow musicians.Watch: Middleschooler Camila Sievenlise talks to TMJ4 about why she walked out Camila Sievenlise"I'm a part of a band and I just really love band, and I feel like it's unfair that they worked 7 months on a piece and got taken away 5 days."Sievenlise said the high school walkout motivated middle schoolers to organize their own protest."There were so many people that walked out in support of people in band, whether they're in sports, choir, orchestra. Like a lot of people walked out. Like half the school walked out, so we thought that maybe we could get like half the school to walk out here."Sievenlise described the chaotic scene when students tried to leave the building."There was a lock and hold because there was something that happened in a class that said a co-principal and a school resource officer running away, so there was a lock and hold drill. Because of something violent. So then after 30 minutes they let us out. They let us out and at the front door we had to have a pass to leave, but then everyone escaped from the door over there and ran out while people were like we all tried to get a walk out and nobody. It didn't work because they wouldn't let us out. So all of a sudden everyone ran out with their signs and their face paint and everything and started protesting."Her message to the school board was direct."Let them play. It's a piece with no words that if they don't know the meaning, you don't know what it's about."Sievenlise also reflected on the broader climate in the district."I'm one of the people that speak up at meetings, so I'm like really happy that I get the opportunity to do that and then that we can come out here and protest for a school that's not even ours, for music that's not even ours, and we all care so much."The school board voted 7-1 Tuesday night to prohibit the Wind Symphony from playing the instrumental piece. The spring concert is scheduled for Monday.On Wednesday, hundreds of Watertown High School students walked out of class to protest the decision, gathering outside the school with signs and chanting, "Let them play."Sophia Anderson, a student who spoke with a reporter last week when coverage of this story began, addressed what it meant to see so many peers show up in support."I'm just so unbelievably proud of all of these people, a lot of them don't even fully know the circumstances as to which they're out here, but just seeing them all out here, these maybe about 200 people, is amazing. Like getting their support for just a band class is the best thing I could have asked for."Anderson, who has been practicing the song for months ahead of the spring concert, described her reaction to the board's decision.Its about time to watch on your time.
