The overall goal of collecting indicia is to show a nexus between your suspect and the house or property you are searching. It is one of the first things the defense counsel will attack, trying to show his or her client was "just visiting" when the big bad cops kicked in the door. Be sure you have plenty of indicia and other ways of proving your suspect was truly in his castle when you stopped by to say hello.
Clothing and Personal Property
What was the suspect wearing when you arrested him? Did you arrest your burglar at night while he was wearing a black jacket, black pants, black gloves, and a black hat carrying a crowbar standing next to a pried-open door? Think this would be an important point to bring up in court?
Most of us would clue the district attorney into this little fact. However, if you don't document it and take photos of it, you will get attacked (possibly successfully) by the defense. Even if the judge believes you as an officer, the defense can (and will) bring up this little zinger, "Why didn't you think this was important enough to photograph or document, Officer?" The defense will likely follow that one up with this hook, "If you forgot this important fact, what else did you fail to document in your 'complete' report, Officer?"
Lawyers love to make officers squirm by using these arguments, so be ready for them by documenting and photographing the exact way you found your suspect: clothes, property, and all. Also make sure you document where you found your suspect and the condition of the area. Was your suspect standing in a nice well-lit street corner waiting to cross the street, or was he crouched behind bushes in a darkened alley? Remember, if you don't put it in your report, it didn't happen.
