I was referee ın Turkey and ı believe system is more basic compared to UK. All games must process with ars and at least 2police officer presence referees have right to not to start the match without police. Also usually police and referres assigned to pitches on daily basis for example there is pitch and on that pitch there will be 5 games on saturday the local fa assinges 3 reffs and choose which refs be de middle and ar by looking their level and level of the match. That system contunies until the regional amateur league which is one step before proffesional league. Usually there is more than 1000+ game per month where i live and that system working wery well just wonder everyone opinions and how this type of system might use ın uk too.
