If I'm reading this correctly, this stated that an officer outside his jurisdiction may make an arrest, as soon as practicable after making the arrest, notify a law enforcement agency having jurisdiction and The law enforcement agency shall then take custody of the person committing the offense and take the person before a magistrate. This sounds to me as the second county would be the county where the charges are filed.

Also, in the report the officer states that it was "unsafe" to make a stop on a lengthy portion of road where he followed my buddy. This is a raod that passes through residential areas with churches and schools, it is far from unsafe to make a stop at 3:00 a.m. as there was no traffic on the road.

Would an attorney be able to file a motion to dismiss based on this, and would a county judge be able to grant the motion and dismiss the case?

Also, you mention "if the cop lies about the county there should be video" Either he lied about the county as stated in his report, or he didn't know what county he was in. How can this be used in this case???
