Which can be a failure in itself when you spend 10 years and tens of billions building something “perfectly” only for it to break on its maiden voyage. That makes you wonder what was the point of doing everything so methodically when they could have taken a more efficient and iterative approach.
This is such a farce that I hear about all the time in the true crime podcasts I listen to. Prosecutors find themselves with a case that has no direct evidence pointing to their guy and 9 times out of 10 they pull a jailhouse informant out of the woodwork at the 11th hour claiming that their guy confessed (to a complete stranger) every little detail of their crime.
Meanwhile whenever someone who may have any sort of criminal record comes on the stand to defend the defendent, prosecutors claim they can’t possibly be trustworthy because they have a record.
It’s a clear “heads I win, tails you lose” situation in the courtroom most of the time.
