Well systems that allow violent people to go round unsupervised or unmedicated (to calm them down, Im not talking treatment as such) doesnt prioritise anyones safety
More men are killed by men, than women are killed by men. We're all at risk from people like this. Look at the recent stabbing on the train
MH services are hugely reluctant to force medication even when detained. Ive worked with clients ( I dont work in MH per se) who have been detained and continue to be ill, but medication is not forced, these are finely balanced clinical decisions.
Out in the community, you have to have someone wanting medication, how do you force it on someone who is out and about and refusing to come to appointments. In his case, it would simply be something like a mood stabiliser, whats his diagnosis? Its not treatable as such. Medics dont like (for good reason) just sticking people on something to calm them down. And certainly not children
In other countries they're less worried about doing that, and equally they are often criticised for how they 'drug up' the vulnerable or stick children on medication to be able to manage them.
Well in my view, sometimes you need to.
