CA jurisdictional issues are not a problem as there are state laws and MOUs between agencies state wide that remove that as a barrier. But, Texas seems to have some limited jurisdictions. My friend works in a suburb outside of Fort Worth, and he says that his ability to enforce the law ends at his city limits, so unless he is stopping someone outside town for an offense that occurred in his city, he can't do anything but call a crime in. However, I am not sure if that is based on policy and practice, or based on state law. It could be that within his county the agencies don't get along so no MOU of any kind has ever been crafted.
I suspect, however, if the officer is knowingly stopped someone who committed an offense in an adjacent jurisdiction that this is not a problem here.
John, you might consider consulting an attorney that specializes in traffic offenses.
