Those who I took in for an intervention were politely informed that if they did not go willingly, they would be informed of their rights and escorted in with minimal force necessary.
So, should I have let them off themselves? After all, it was their right to choose.
As I pointed out earlier, by voluntarily joining the military they entered into a contract in which they gave up some rights. Given that, your actions were just fine.
Had they been civilians, it would be different, of course.
