Perhaps so, but it raises another question, I'd think. Namely, why was the defendant apprehended so quickly and decisively? As you noted, there are over a thousand safe-deposit boxes in that room; the defendant may certainly have seemed suspicious to some, but the manner of her capture seems more to suggest they were not merely suspicious but immediately certain of guilt.

I can certainly imagine a number of explanations for why that might be the case, but it does seem starkly at odds with security being lax enough to miss a malfunctioning surveillance camera.
