I don't get the whole "but they were UNARMED" thing.
Okay so you might not have a firearm, but you could have been armed with other things. A knife. A rock. Your fists.
If you give a gun to someone who doesn't have a clue what they're doing (me), and you have someone who's pretty good in a fight, the 'armed' person is gonna lose to the 'unarmed' person.
Unarmed means unarmed. If you look up the definition of "armed" you'll realise it doesn't just apply to firearms.
