not only can you not prosecute the other offender
Why not he still broke the law.
as a police officer you are pwerless to do anything anyway.it is a game law and up to the local game warden to enforce that law
A policeman can arrest someone for a game violation. Seen it done. Or he could hold the person until a DEC officer can get there.
You trying to tell me that if a cop witnesses you shooting a deer illegally he can't arrest you? Let's say for example if you were to shoot one at night out of your car window? What State were you a cop in?
