I read it and i get a kind of 'You call that a serial killer? Pah, thats not a serial killer' type feeling from it.
Which to be honest seems a bit off, because surely it dosen't matter how many murders take place, they're still bad.
Also, with your justice system, how do you mean an institution? What sort of term are you talking? For the guy committing all these murders in the UK, (5 so far), he'll probably be out within 20 years, easily. Free to roam the streets.
Still, at least it's not like i'm paying for this sort of scum to have 3 square meals a day, a roof over there heads, and in most prisons the option to take degrees and stuff. Oh... Wait...
