This! So much this!
My eldest (a boy) had a terrible time when puberty hit as it made his autistic meltdowns seem really scary (he went from little boy to over 6 ft within a single summer). We had police involvement three times and they were truly excellent with him. The one time he was arrested and driven away from the family home they immediately made arrangements for my best (male) friend to be his approved adult and released him to stay overnight with said friend within an hour or two.
They then made arrangements for my son to attend a Youth Offending Team appointment, which wasn’t in the police station but in a neighbouring building, and the YOT referred him for Multi Systemic Therapy via the NHS (something we wouldn’t have been able to access without the police involvement).
He’s 23 now and has no other contact with the police (except when they returned a lost wallet!)
The police are actually able and capable of being really helpful with autistic teens, shame this particular bunch was so power-mad and ableist because any parent of an autistic child who has seen that footage will be thoroughly put off from contacting police themselves in future.
Which ultimately will be bad for the parents and autistic teens who would actually benefit from a little police involvement (as we did) and bad for society as a whole because being able to trust the police is part of a functioning, democratic society.
