I personally think a "Hand Cuff" Should be added for cops. Because has anyone been in a gunfight with a cop and they will strafe you and just Arrest you? It would also prevent Mass RDA. Since It gives the player time to react while letting the cop get the real experience. People will be saying below how this is not Serious rp. But it would benefit a more rp experience other than running to a guy with a red stick and hitting them. They would have to be cuffed for the to be arrested.
The handcuff-system is better option than to the arrest button system that we are currently using, of course in my opinion. Maybe you can only hit anyone with the arrest button while being handcuffed. But there will be the problem of course when people aren`t RPing and just gonna run away with their guns in the hand and you can`t stop them since it takes a little while to apply the handcuff, but of course we can find a solution for that.
