I really don't get the point in discussing this but fuck me I'm going in.
First of all, your arguement is not solid enought, you all said that even in cuffs, you can reach your radio and talk, let me show you a pic:
Here you see a person CUFFED, maybe inside the server the animation or the preview of a cuffed person is with their hands in front of them, that's why your arguement seems "valid", but let me tell ya, that's not a valid reasoning, you're just all supposing that because of that, every person should be able to throw their hands to their radios like monkeys and say a word.
And let me tell ya something more! Is not only being cuffed, is that you can be under GUNPOINT, remember that classic FearRP? Oh sure, it's optional, oh sure, I can still talk in comms while cuffed, because I can (but you shouldn't). You CAN do many things, the thing is, this is "supposed" to be a RP server, not a 100% RP one, but let's try to at leats, feel fear, do a little of FairRP with the players, and don't do stupid things you would never do in reality.
