Back in the days of 0.1, the first skin in the class selection was the police skin. This was removed because it was thought that newbies were joining the server and getting spawn killed.
When it was the first skin on class select all the newbies just entered the server as a police skin, this was seen as 'bad' because regulars came to this place for some easy kills -- it was becoming known that the newer players spawned here.
I disagree with the removal because from experience this place was a lot of fun, it was a mini deathmatch arena.. If you join the server for the first time and see lots of players here, it makes it a very exciting place for deathmatch players. More victims, more challenges. Players who do not want action when they spawn can pick another skin, or join a pure roleplay server.
