people don't have unlimited lives, you get one life per roleplay (unless its a chase where police are allowed to re join after death as new characters)
About the shooting part, we are not a DM server, and shooting should be avoided or kept to minimum use.
Plus the sync on the server isn't working so you can shoot as much as you want, but if you didn't go over LCPD Basic training where they teach you how to shoot so you might actually hit your target, chances are you will never win a gun fight.
So i advise you dont use guns, if you get shoot at for no reason /report and let admins handle the DM
