In my experience so far when I go into the new spawn area towns near Bolota new spawns are just sprinting around trying to sneak up on geared players and try to get the knock out punch for easy gear. Even while asking if they need help or want food I've encountered so many unarmed players try to kill me the very second I'm not looking directly at them. I've even started to bandage a wounded player after killing the zombies chasin him and he just starts punching me! Now, if they are far off in the distance running away and causing no harm I wont fire.. but get within 20 feet your pretty much dead. As for camping jails and knocking out server hoppers when they are loading, go for it.
