You have to keep it in context Stormie. Within the parameters of that "world" those actions were legal. For that matter, since we're talking "Robocop" after all, his actions were programmed...it'd be like suing a computer for messing up.
And then let's get literal. Given the particular circumstances for that "crotch shot" I don't think it would fall under "cruel and unusual" anyway. As long as a court could find use of lethal force justified then where someone was shot is actually irrelevant. Only possible exception might be that if it could be shown that other target zones were available and that the groin was targeted expressly for malicious intent. As I recall they framed that scene expressly to make that particular shot viable.
Fine they may be legal there but I doubt you''ll find a cop in the USA using these same actions with no legal problems which is my point.
.
Why did uphold the law come up when he was choking Clarence because it was attempted murder which is a huge violation of the law a felony to be exact so that is not legal it is illegal.
It's unlikely a cop with body cameras now would use attemlted murder while on camers that but lets just say one did use attempted murder whether on camera pr not but was stopped or stopped it's a safe bet they would likely get fired, and go to Prison.
There are lethal shots which are ones that kill the criminal and non lethal which defeat a suspect without huge alterimg damage to their bodies. Shoulder shots are very common.
Lethal force can be justified but I doubt a cop shooting a criminal in the testicles even if no other area didnt appear available is going to be upheld as justified.
Blue Bloods
Danny decides to take a blowtorch while on then point it close to the mechanic's face to get major information while threatning if I recall right to hurt him in a specefic way with the blowtorch if he doesnt give him the needed information.
Truth
I don't doubt at all that a Detective or any cop in the real world specefically the USA can't use those actions to get information from a person without huge problems with the Law.
Spoken verbal intent to harm spefically with a deadly weapon, coercion, threatening a human with a deadly weapon yeah its pretty much a slam dunk they will have legal problems if they used the actions above.

Factual Error
In this movie British Soldiers have Repetion guns shootong at Jack Sparrow when he is running to escape.
This is impossible for the time as Repetion weapons didnt exist until the mid 1800's.
