You should be okay. A friend of mine is going through a similar situation now. He was the pnf when the pf clipped a tfr. The pf was cautioned repeatedly about said tfr by atc and the pnf. The feds are going after the pf as he was the pic and his name on the flightplan. My friend has not had talk to the feds--the other guy has though. Cut and run if you can. Good luck.
