What does a panic button trigger? That would be the question. Would it be triggering the local police department? If that's the case, I know that where I practise, the Peel police are extremely overwhelmed. Despite the increased budgeting, they're still struggling to deal with the sheer volume of calls that they have. By the time the call is attended to, often the event has already transpired.
It's a very challenging situation. Aside from putting up signs, creating barriers, installing cameras, etc., there's very little that front-line physicians within the community have available to them in terms of addressing the violence. With legislation such as MP Davies has brought forward, patients would know that there are serious consequences for their actions, and it would help to create a significant deterrence to that type of behaviour.
