Spawn a Police Partner in. Press F3 - it uses the Native Trainer example GUI for selection. First select a partner type, then back out and select spawn (same keys as Native Trainer). Currently the limit has been removed to spawn Officers, and they are unarmed - later I'll be adding to make them come with realistic loadouts, the K9 partner does not currently load into a vehicle, but will be corrected in the upcoming versions. He will however tackle a person that becomes a combatant. :D
