What will they argue? How will the prosecution likely respond?

“Fast” Eddie Jones is cruising down the highway in his tricked-out Honda when he is pulled over by a police officer. The officer runs the plates and discovers an outstanding warrant for Eddie’s arrest. The policeman immediately detains Eddie and conducts a search incident to arrest and finds a small amount of meth-amphetamine on Eddie’s person.

The database used by the policeman was out-of-date and needed to be updated. Had it been updated; the database would have NOT shown any outstanding warrants for Eddie.
