When entering new questions, KudoZ askers are given an opportunity* to classify the difficulty of their questions as 'easy' or 'pro'. If you feel a question marked 'easy' should actually be marked 'pro', and if you have earned more than 20 KudoZ points, you can click the "Vote PRO" button to recommend that change.
How to tell the difference between "easy" and "pro" questions:
An easy question is one that any bilingual person would be able to answer correctly. (Or in the case of monolingual questions, an easy question is one that any native speaker of the language would be able to answer correctly.)
A pro question is anything else... in other words, any question that requires knowledge or skills that are specialized (even slightly).
Another way to think of the difficulty levels is this: an easy question is one that deals with everyday conversation. A pro question is anything else.
When deciding between easy and pro, err on the side of pro. Most questions will be pro.
* Note: non-member askers are not given the option of entering 'pro' questions; the only way for their questions to be classified as 'pro' is for a ProZ.com member or members to re-classify it.

Discussion
make it active please...
Police-speak or no, this is just OTT
Eliza, any chance of you running English lessons for your local police?
Although this term isn't on it, this is a great resource if you're translating US police/law enforcement documents:

Wouldn't "This subject has an active custody" mean that "this subject" has something/someone in his/her custody???
If it was about the prison system having custody of this prisoner, wouldn't that be:
"This subject is in (active) custody"???
Any more context (as in: the original text, not comments about the ST)?
Yes, this is referring to the prisoner, not to an active custody of a child.
Thanks for asking :)
Nicolas, can you confirm the context -- custody of whom?
