Maybe add more customisation to guns like for example Officers can have flashlights on the bottom of their sidearm and civs can chose sights and silencers ect ect.
ADD a seat belt option because in the fx server when u hit something at high speed you fly out of your car so this would be really usefull and again would add to the realism
Actual Handcuffs on the suspect that you are arresting cause most of the times the suspect does not know that he is cuffed plus it would add way more to the realism and would look so much better - Thanks Jake
