"See this photo? yea, well this photo got me and my gf suspended from our high school for 10 days. possible expulsion too. Today we were taken right before the Cross Country states meet. We were asked, “why would you post something like that?” when we tried saying something, they told us to be quiet and they separated us. I was sent to a room and my bag was searched, along with my clothes and locker. The school called the police and they had a cop speak to us without reading our rights and without our parents permission. We had no say in what happened and we never got a chance to defend ourselves. We are both out of school now, in a school that only allows 4½ days absent. Which means if they don't expel us, we pay for overpriced saturday school and winter school. I understand it was wrong to take a picture with guns but come on. My dad took the photos, in my house. The guns were pointed at the floor, on safety, mock mags in, and our fingers weren't on the trigger. We had a responsible adult and he isnt againts airsoft. He knows gun safety and he keeps my guns, i dont have them unless im out at the fields. Well the dance was friday, and it went perfectly fine. No fights or anything. Today is monday, and now were both defenseless. The school took away whatever rights we had about speech. Our parents didnt have a say either. In 10 days we will have to have a conference with the school board, they will decide if we get suspended or not. I think its bullshit that we get suspended over a photo taken at my house because it was “threatening”. If my school wanted to suspend everyone who posted a “threatening” photo, then i couldnt have a photo with a car because cars kill people. honestly i think its unfair and its not right. My school could care less if you post a picture of you smoking or getting drunk. but you post a photo of a gun and everyone loses their mind. So right now im trying to get this story out to people to try to show that the school is wrong and that it wasnt a threat to anyone. The school is Bristol-Plymouth Voc/Tech in Taunton, MA. Please help me out guys., thanks." 

It's a problem with taking away our rights. They have no jurisdiction over your happenings unless it directly pertains to the school. 

schools may regulate any speech which causes or is likely to cause a substantial disruption of school activities or education in the classroom. Anything that directly affects the school. ex: Slander; bullying of another student; or any other expression that disrupts the school or causes a peer to miss at least one day of school.
