My sentence-by-sentence reaction to the underlying facts of this opinion:
"After several gang-related shootings in and around Union City, officers from various jurisdictions formed a plan to arrest suspects they believed were using a stolen car."
Great. Let's stop those shootings.
"The night of June 18, 2018, officers located the car and followed it in unmarked cars as it traveled throughout the area."
Sounds good. Like what you see in the movies.
"The car began circling a Union City neighborhood associated with the suspects’ rival gang, and the officers decided to execute a “Vehicle Containment Technique,” in which one police vehicle “stops in front of the suspect vehicle and reverses into the suspect vehicle’s front bumper” while a second police vehicle “simultaneously closes in on the suspect vehicle from behind until the bumpers are locked and the suspect vehicle is securely contained between both officer vehicles.”"
Seems like that's a great plan, and would work well.
"Two Fremont police officers initiated the technique when the suspects’ car was stopped at a stop sign."
Seems like the perfect location. What could go wrong?
"Occupants of the suspects’ car immediately started shooting at the officers."
Oh, yeah. That.
In retrospect, I guess it's not surprising that gang members suspected of various shootings might react negatively to being deliberately boxed in by unknown occupants of other vehicles.
