Hmm,

I wonder if thirteen rounds of 45 acp is enough to perforate the roof panel such that I can brute a hole out the top regardless of what's bolted and how? Maybe that and the can opener blade on my Leatherman Wave?

Other than that, I don't often bring a breaching charge with me in public.

In any case, were I stuck in an elevator, I pity the fool who has to come and repair it after I am done with the thing. Also, more pity for the butthead that either decided not to include a monitored alarm system on the car, or the one who chose to ignore my gesticulations for two days.
