In all honesty the only server that has a huge cop base is server 3. Most other servers have around 8-10 max. Running in groups of 2-3. It is very easy to kill them, and when you do you should fully expect more cops to respond. Failing to figure out an way to get away or foolishly staying in the area after you kill them is honestly your fault. There is no NLR on this server, rebels abuse is just as much as cops at times.
