FYI: my daughter was never given the opprutunity to be in a general education environment. My daughter was moved from her special ed preschool class to an SLC for "screaming". Her teacher did not care to address or make modifications to her IEP, she preferred to send her to the SLC because that is where "all the autistic kids go". So my daughter graduated from screaming to scratching and was then flushed to Mt.I because her principle intervened in the IEP team meetings and denied the TEAMS request for my daughter to interact with pro social peers during recess and other structured activities. 
So my point is this, your system is broken and it did fail my daughter. My daughter never needed to be in an isolation room or to be fully restrained. All she needed was redirection and light physical guidance. 
My point is that these kids have an individualized education plan for a reason. It is to avoids generalizing them into populations labeling them as "violent". Because some are NOT violent
