Attorney (and wannabe) Advice Sought - Negligence

[grandllama]

Thought I would ask on the board to our resident attorney's and law students...

As I posted last night, my storage unit was broken into over the weekend and a considerable amount of dj equipment was stolen.

My question concerns the storage unit operators.

Access to my storage unit was gained thru an unlocked, unrented unit on the poorly lit back side of the storage building. The thief(s) then burrowed holes through the walls (drywall / wood construction) of five other units before coming upon my storage unit. My storage unit was not full and the thiefs had access to the bolts holding my latch on and we're assuming they used tools stolen from another storage unit to remove the latch from the inside, then opened the door and removed my equipment and equipment stolen from the other storage units.

In my eyes, as entry was gained thru an unlocked, open unit, that management had known about for several months, the storage unit management was negligent. (Side note, the police also found another storage unit that was open that someone was living in)

Other opinions?
