You cant ziptie in the greenzone, and you probably could, if you initiated rp you couldn just run upto them knock them out and take them there, there is a bounty hunter job tho :P
Mhm prefer the more on the beat look, formal trousers, boots, tooo tracksuitish for my liking, also i think having the vest visible is much better, cant add a police to the back of the vest? maybe high vis jackets for those who wish to wear it :P ?
