Cops and fire usually get along as you work the same scenes together quite often but the CHP is a different breed altogether. They are often referred to as "AAA with a badge". Most cops won't ticket other cops if they pull them over and will extend professional courtesy, but that's not the case with CHP. They will ticket cops all the time and it's 50/50 at best if a chippie pulls over a firefighter.
The incident five or six years ago went rather viral out here and didn't help the chippies relationship with fire much. CHP owns the freeways and they get rather pissy if you don't park a certain way. Granted some engineers and captains will park in a way that takes up way too much room and impacts traffic, but some do it just to tweak the chippies since that last incident.
What I've heard is that there was fault on both sides and the engineer was blowing off the chippie completely when asked if they could move the rig a little so the backing up traffic could get one lane to get by. The handcuffing was just way over the top. CHP looks bad but internally both departments could have prevented this.
