If they can do it in England, Sweden and the United States, why not do it here?
I don't think that's a real answer. I think we deprive ourselves of people who can help us if our employment standards are too low. If these people come in and can't satisfactorily complete development programs, we're harming more than helping the police. So I don't think so.
What's more, that might create two employee classes: ordinary people who have some education in one, and indigenous candidates and recent immigrants who have none in the other. It would thus create a kind of ghetto within the police force. I'd be very afraid of that.
