My favorite arrest so far:
ALPR flags a van for having expired tags so I pull them over. Walk to the car and get the IDs for both people. Run the driver who has a warrant, passenger was clean. Pull the driver out, frisk her, find a weapon, and detain her in my car for the time being. Ask the passenger to step out and he books it. Chase him a few feet before I deploy my taser. Frisk him and find stolen cards. Search the vehicle and find a weapon. Arrest him and call for a transport. Charge the driver (arrest her) and call for a wrecker.
