I dont know where you learned to english. But from my decoding I think you want Riot Officer, Special forces, and Swat Commando on the Civil Protection job tree as well?
Yeaaaaah, No. That would never, ever, in the history of ever, happen. We have job trees set up the way they are supposed to be... aaand that assassin skin doesnt really fit into RP... you know... having a medieval guy running around with an M24 wouldnt really work.
