Experience shows that this effect does not occur to the desired extent.
Less irreversible than execution. Also, it's easier for a person to sue for tons of money for wrongful incarceration than for the estate of a person to sue for tons of money due to wrongful execution.
And suing for lots of money is necessary to motivate the voters/taxpayers to keep the rate of wrongful convictions down. If wrongful convictions aren't freakishly expensive, there's no motivation.
Now let's see:
a) The method requires some skill on the executioner's side.
b) It's messy and doesn't leave a pretty corpse.
c) In some cultural contexts, death by bullet is considered too honorable for criminals.
d) It's quite destructive. If person-to-be-executed wants to donate their body to science, science gets a body with a hole in it and parts missing.
That's because it started out large enough to have quite a bit of momentum.
In putting your own mask on first, you are thinking of the children. It takes more than one minute for permanent brain damage to occur due to hypoxia, but without a mask, you only have about 15-20 seconds of useful consciousness left in a worst case case scenario.
So, put your own mask on first, then you'll have plenty of time to put the masks on everyone around you, including children and people who didn't know the basics of respiratory physiology.
Even better: If you're suicidal and have a gun, you can just get it over with and shoot yourself. No need to drag 149 people with you in a suicide-by-airplane.
Managing lots of things competing for their attention is what pilots need to be excellent at.
That's why you lock the door first. Also, are pilots being scanned, searched and groped for anything usable as a weapon even half as thoroughly as the passengers?
Right. Being a pilot requires excellent executive functions.
Someone who can't get the tasks "lock door", "incapacitate other person in cockpit" and "fly plane into ground" in the correct order has no business at the controls of a plane!
Right. A pilot trying to kill himself and everyone else on the plane by flying it into the ground will absolutely not kill the other person in the cockpit that may be trying to stop him.
Sorry, but having two people in the cockpit is a safety measure, not a security measure. It helps if one pilot has a heart attack, but it does pretty much nothing if one pilot is a suicidal, murderous maniac.
The black or Jewish printer should make every attempt to out-bid anyone else for this job. The resulting
Yes. The KKK would be shooting itself in the foot if they pulled something like this, so it's not going to happen. It would be quite funny to see what the consequences would be, though.
