Conscription doesn't have to be active military.
It can be any national service and it would be
great if one were created to instill some order.
Now this I agree with, but the idea that it is done to "install order" makes me nervous. That kind of language smacks of the 1930's. Such service has to be more about making people understand that society is a collaborative effort which requires a certain amount of compromise and teamwork. An airy-fairy pipe dream on my part perhaps, but it serves no purpose if it does not teach anything useful. It can't just be about restrictions, is has to be visionary and empowering as well.

Oh please. For starters it's called the Army Reserve now and has been for some time. Also I suspect you don't understand the role of the modern AR, or the needs of the regular forces. We need trained soldiers, not more part timers (though they are valuable), and giving an offender the chance to be prt time soldier is pointless.

I don't know if you've ever tried to leave a military base with a weapon when not on deployment, but it's not exactly easy. Not quite sure what point you're trying to make, but the Army tends to have its weapons under tight control, and those same weapons are very hard to come by on the black market. Certainly if you mess around with one on base you're going to military prison.
The Army is actually very good at teaching people what firearms are like.
