You are somewhat lucky it wasn't from your house. I'm not in the area of the city where this happens, but in some areas they break into the house, take the stuff, and come back in 6 weeks and take the new stuff.

Insurance. They are in the business of keeping your money. I have, as suggested, used an etching vibrator pen to mark my stuff. My Social Insurance # is on it, 9 digits.

And the list, filed with my insurance company. They love to tell you a rider was required. I just say here:
Photo gear: x y Z etc.
Music Gear: l m n o etc...
Tools : a b c d...

with serial #'s, my marks, and digital photos, along with bills etc.

And I always pay with visa, I have extra insurance there.

It does help to have spent many years working with Insurance Adjusters. They have some odd quirks. A mis-step causes HUGE delays, and your file gets kicked around.
