Down in SD at least, the sheriff's office helicopters serve many purposes. They'll use them for firefighting, hike rescues (often! according to their IG), first responder to an aviation accident, loudly shouting garbled messages through their loudspeaker, etc.
There's just enough high-speed/timely crime here that I prefer they use these over drones. There's some extra legal protections built into helicopters that drones don't get, like prison time if some idiot points a laser pointer.
I seriously doubt that physically rescuing hikers or delivering first-responders to plane crashes represent a large percentage of LAPD helicopter missions. I live in a nice suburb and there's one of them circling over it probably weekly.
I don't see why large drones can't do most of what these helicopters are doing. They're using needlessly expensive helicopters, too.
I work with CHP helicopters as part of our fire district's rescue team. We pull a half dozen people a year off of one of the local trails (sometimes as "recovery"). Most of these are via helicopter. There are two helos for a huge area - Yolo county down to Santa Cruz county. By acreage it's a lot bigger than LA.
My point is, two small helicopters are more than enough to do that job as a side-gig from all the other CHP work they do.
Also, Cal Fire has its own air wing. LAPD helicopters are not equipped for firefighting.
In SD, we have cal fire helicopters, sheriff helicopters with water tanks, SD City Fire Department has their own, and I just learned SDGE (electric utility) has their own firefighting helicopter.
It's absolutely worth looking at the ROI on these flights and weighing that against the intrusion on our privacy/freedom. No doubt they'll always need drones and helicopters but I'd be surprised if there was any real need for them to be in the air that often. I think that's a question that should be asked everywhere but the LAPD in particular are terrible enough that it makes this a great place to start.
I was in Santa Monica - the dense part with all the alleyways - during a foot pursuit involving a heli. Felt like I was in vietnam. It was at night, they were pretty low, and that light felt like the sun coming into the building.
That depends on the drone. There are drones/UAVs that fly so high in the air you can't even see them seeing you from the ground. Even low flying drones would be very hard to hit from a car involved in a high speed chase, and it's not as if people can't shoot at helicopters which are both larger/easier targets and much more dangerous if brought down.
You're talking about technology that's only become realistic in the last couple years. Even then, there's probably nothing off-the-shelf that would serve the current need.
LAPD has been patrolling with helicopters for decades. I have yet to see a drone follow a car in high speed pursuit down the 5 at 100+ MPH.
As far as I'm aware, high speed drones tend to have quite short flight durations due to battery limitations. Drones that have the range to follow a fleeing suspect for a long time would probably have to be big enough that they could cause a fatal accident if they crash, and in that case I'd rather have a pilot on board. Better reaction time, no risk from jamming, much better field of view/awareness, decades of testing, etc.
Most of the small high speed drones are that size to fit under professional licencing requirements, often so that one racing spec can be viable across a wider area.
Leading to significant competition in that size pushing down prices.
Rather than some inherent sized for safety idea.
Jamming might be interesting, I suspect that it's easy enough (and a much bigger crime) to follow a very loud jamming signal though.
Every practical metric a drone surpasses a helicopter; they are so much simpler to operate that you can easily offset any perceived downside with more drones. And you don't get a tested solution without trying it out.
> why do we allow high speed pursuit chases in the first place?
AFAIK they've changed their tactics in recent years, but growing up around LA these we're like sporting events on TV. It's a guilty pleasure, but almost everyone I know tuned-in and watched the chase.
Their popularity for viewers (even more so now with YouTube, but they’re long been a staple of live news and late night tv) and the fact that police like any excuse to do “badass” things are big parts of why they still happen. They’re a pretty bad idea. Endangering lives (including bystanders) over mostly relatively-minor crimes.
But people love ‘em, and if you point out what a bad idea they are people label you “soft on crime” (as happens with a lot of plainly good policy)
These needs should be filled by drones. Way less noisy, dangerous and expensive.
