Numb3rs Fanfic Finders

I was reading some NCIS fic and came across one where one of the agents became a vigilante after becoming disillusioned with the system. This got me thinking of Don and the stress of the job that has gotten to him... does anyone know of any fics where he became a vigilante??? Where he started taking justice into his own hands when a criminal was too smart to leave concrete evidence or got a lawyer that got him off???
Thankie!!!
