They try but it's not legal and in the cases we get to hear about, the police always issue an apology.
But no, the person doing the arresting does not get to decide if it's an arrestable offence. That is dictated by law.
They do, at the time the arrest is being made; obviously, that doesn't mean they're right, but it does mean that people here and there do get arrested for things that are not an arrestable offense. I think we all know that the police can't make up their own laws, but try to stop them from enforcing one when they're sure it exists.
