after living there for the college years.. it was pretty fun.
UCPD, SBSO, CHP & Search and Rescue come together as the "Isla Vista Foot Patrol. They operate on their own channels, but monitor eachother.
SAR will set up about 2-3 command posts at various intersections of the city. IVFP usually will "clump" and walk in groups of 4-5. I used to scan them when I was up there, and just remember pure chaos.
