Ok, I'll "bite"--even if I'm just participating in absurdity.
I live in Arlington, Texas, a "destination" city--I'm actually within a mile or tow of the Ballparks, Jerryworld, and Six Flags--so there are a lot of visitors from other places and a tone of service jobs. As our economy still has not fully rebounded, there are a lot of people working more than one service job at a time (about 1/4 of the waithelp are uber/lyft drivers). People asleep in their cars is not uncommon.
Most of our international visitors are just too agog to much notice things like people sleeping.
Now, if the PD were called to examine such a situation, Texas law forbids a non-concealed firearm within a motor vehicle. So, PC would exist to rouse the passenger and have them speak to the actor--that is, within the limits of Texas Castle doctrine considering autos.
I'd like to think that, after a couple of minutes of non-responsiveness, that APD would roll EMS to insure proper health.
Because, that's what irritates me most. Let's say the dude in CA was working a bunch of jobs. Let's say he was on HTM or blood thinning meds. It's real easy, when you are tired, to not get enough food in you while on those meds. Which means you can get vertigo and slip out of consciousness from hypotension--low blood pressure. A hypotensive patient is not well served by not getting EMS care for FOUR HOURS.
I mean, really, what would Alhambra SWAT had done is this guy had died from medical inattention in that four hours? Said, "Oh, well, he shu'nt' orta dun it?" What if one of the innocent bystanders cooped up in all those stores had had a medical issue?
I strongly suspect that the problem was in that the actual first person on scene occupies a desk far too close to the Chief, and not enough time in a radio car.
