We need a new method of execution

The recent failed execution of Pike has shed light in the issue.
>over 7% of lethal injections are botched
>electrocution is agonizing, with 2% being botched (people catching on fire or otherwise requiring a multiple jolts)
>gas chambers create a serious chemical hazard for staff, including the dead body
>hypoxia is just straight up horrifying and unpredictable

A 500kg mass falling 10m produced around 49,000 joules of energy. On a theoretically completely rigid stop, this would result in something outrageous like 49 MN (49,000,000 Newtons).

Now, the actual force produced depends on stopping distance. A 1 meter stopping distance would result in 49,000 Newtons. 10cm stopping distance would be 490,000. It’s the basic work-energy principle.

It only takes about 2,400 Newtons to squish a human skull like a grape.

Imagine two 10m (30ft) vertical poles roughly three feet apart. Between them is a 1m lo...
