I noticed that in the books, there's a canon example of a Death Eater attempting to use Accio on the Invisibility Cloak, but to no avail. There's also one where Harry says "Accio Firebolt" and his broom comes flying to him
My understanding is that the spell calls the item with magic, so by all means it should have worked.
My theory is that you cannot use the spell on items not owned by you (for obvious reasons), but that it is possible to Accio literally anything (Exampled by Harry's Accio of a dictionary from Hermione).
I read in What are the rules and limits of accio spell? that concentration is absolutely necessary to cast the spell, but what sort of protection is there against a poor wizard plopping into Gringotts and saying "Accio loose Galleons" or other such things provided the wizard was concentrating hard enough, and what rules are there in the Wizarding World for theft and other petty crime from this spell?
Note Slytherincess noted in the answer that rarer items are harder to Accio, but as Galleons seem to be no big deal to some witches and wizard. This doesn't say anything about apparition or other spells though and I suspect the enchantments would be specific counters for specific spells.
Question: What are the forensics the Ministry uses for crimes involving theft with no physical evidence from the thief?
Bonus points if you have canon examples as to the Ministry's forensic techniques regarding magical miscreants!
"Alohomora locked chest with an answer..."
EDIT: I used Accio as an example, as it's the most common, but I also was hoping people would also think apparition, Alohomora, Bombarda, and other spells that a prospective thief would find useful. It's meant to be what forensics does the Ministry use, not limited to a narrow view of a single spell and what it does.
That being said, I did find the answer to the single example given in How do wizards prevent Accio-fueled robberies?
EDIT 2: I realized that I'm a bit stupid and tired at this point, and once of the words I used in the actual question was wrong. I apologize to everyone for the miscommunication.
EDIT 3: I'm not sure why the entire question wasn't read by the community, nor the edits. This will be the last edit and I will let the chips fall where they may, simply because this is getting closed votes without a full read-through.
The ENTIRE question doesn't revolve around a SINGLE SPELL. Prevention (Anti-theft devices) is COMPLETELY different from forensics (Where the deed has already been done). In one of my edits, I clarified other spells as well with Alohomora, Apparition, and Bombarda, just to name a few spells that could be used for thievery. I want to know HOW DOES THE MINISTRY CATCH PEOPLE WHO STEAL, not HOW CAN THEY BE PREVENTED.
tldr; THE ACCIO EXAMPLE IS JUST AN EXAMPLE. I will bold other things that are being glossed over. Vote as you must.
