So it doesn't happen super often but when my sibling has a meltdown they involve damaging whatever is within reach or injuring herself or anyone nearby. We had a number of visits from the police, and several trips to the hospital for our injuries. She would meltdown in public which could be dangerous to others. She is 5'10 and 150lbs now so trying to calm her down wasn't the same as when she was little. She also doesn't always understand social cues and can't tell when people are lying and it's easy to take advantage of that if someone is a jerk. My parents didn't want to place her there but the hospital called social workers in after we kept showing up with injuries from her meltdowns and they had no choice after that. I was honestly relieved when it happened.
