I'm maybe a maniac but, I always keep my aeg's and pistol inside a locked out armored cabinet (like the canadian tire's for firearms).
I also deep engraved my nickname on many parts of my aegs and pistol (also painted my nick on my gear) and keep every pictures of em on a private web server. (we should all do the same for everything at home for insurance proof like TVs, PCs, consoles...)
You did great of showing the pics and let know everybody of the robbery. good luck.
