The UOSA Patch
"Forensic Evaluation will reveal a perma gray thief"
Ok, I'm absolutely positive that this was never the case at any point in the history of UO. Lets take a look at every Official UO patchnote pertaining to Forensics..
Thieves Guild, new skills, and more Feb 24 1999 1:06PM
The introduction of Stealth, Detect, and a bunch of other great espionage themed changes. This patch included a slight modification to the Forensics skill to give it more use.
Forensics
Using this skill on a player will reveal their affiliation with the Thieves Guild, if they are members. The difficulty of this is based on the thief's Stealing skill.
If you have a certain level of ability in the skill, using it on recently picked containers will reveal who the lockpicker was.
The professional title for this skill is now "detective."

This one gave us the ability to use many great skills and remain hidden.
"The following skills will not unhide you when they are used: Detect Hidden, Item Identification, Anatomy, Arms Lore, Animal Lore, Evaluate Intellect, Forensics Evaluation, and Poisoning."

Several click-target skills had a reduction in delay. Including Forensics.
Skill delays for the following skills will be shortened to one second.
* Animal Lore
* Arms Lore
* Anatomy
* Item Identification
* Detect Hidden
* Enticement
* Evaluate Intelligence
* Forensic Evaluation
* Sprit Speak
* Taste Identification
Forensics originally only told you some information on corpses. From it's creation up until the above listed notes, there were no changes to the skill.
UO.stratics.com currently has this information available on the skill...
* Using Forensic Evaluation on a corpse will reveal the name of the killer and of those who looted the corpse.
* Using Forensic Evaluation on a player will reveal their affiliation with the Thieves Guild.
* Using Forensic Evaluation on a lockable chest will reveal who has recently picked the lock of that container.
and this from an old Stealing Guide...
To see if someone is in the Thieves Guild use the Forensic Evaluation skill on them. The higher your Forensic Evaluation skill, the more chance you have of finding out who's in the Thieves Guild.
Here is something that I think we all enjoyed reading back in 1998-1999. The Detective Profession Essay.
Here is a quote from the essay..
This skill is relatively easy to raise to 90, if tedious, with apparently marginal incremental benefits. Raise it by use on anything that has had a crime committed on it. Simple. So, go to the box room in the Warriors Guild in Britain, or anywhere where urchins open boxes, steal etc. Try it on corpses, animal or human. It is a pain to raise, boring etc., but will work. Also try beggars, NPC thieves and thief guildmasters.
Why raise it? Firstly you fail less. Secondly, you are a detective, it's a kind of have-to-have skill. Thirdly, at higher levels you can blow thief disguises. Don't kill yourself to GM it though.
I remember "higher levels" as being 80.0 base skill. I actually worked this lousy skill up to gm on the first character that I ever created. While granted "blowing off a disguise" was fun (albeit pointless), I will never forget how annoyed I was that it would not tell you who is/isnt perma.
Another intresting thing to note about the skill is the wide-spread rumor that.. (quoted from the essay)
"using Forensics Evaluation on you, you can be noticed a lot easier 2 minutes after it's used on you."
There is no "official" mentioning of this, and I never once could tell a difference in the "difficulty" of getting caught, and yes we did perform a double-blind of sorts. I think this one is along the same lines as "food makes you gain skills easier", which we know now to be false.
"To reiterate, even if the skill tells you "This individual is a thief" you cannot attack him in town, unless he is otherwise gray or perma. You WILL be guard-whacked. Outside town, of course, you can pick a fight, sure in the knowledge that there will be no count, but it is of course at your risk."
Okay, This essay was changed post-t2a, sadly stratics is horrible about placing dates on their essays/works. What is listed now goes against my personal opinion and everything listed above...
"If you are a member of the NPC Thieve's Guild, any player who successfully uses the Forensic Evaluation skill to reveal your membership in said guild may either attack or steal from you."
!!??! But what about this quote from above..
"To reiterate, even if the skill tells you "This individual is a thief" you cannot attack him in town, unless he is otherwise gray or perma. You WILL be guard-whacked. Outside town, of course, you can pick a fight, sure in the knowledge that there will be no count, but it is of course at your risk."
I firmly believe that this (false) statement is the cause of this whole argument. I'm going to use the internet archive to check the page
http://uo.stratics.com/content/reputation/flags.shtml
to determine when this blasphemy was added. After all, it is an essay sent in by readers of the website.
Edit: The internet-archive started caching this page in 2002

Lastly, I noticed that Forensics works on previously lockpicked containers, even with a skill level of 0. While I know it's not difficulty based, the skill level should be your % chance to successfully tell who picked it, if I'm not mistaken.
