My second concern - and I am not a lawyer and recognize that local laws will impact this -

Say you are knowingly inside a no carry posted place of business and have to use your firearm.

Are you not subject to civil lawsuits from everyone in the place - owner, employees, customers, the "victim" -- those walking by, those in the next business owner.
You knowingly put their lives at risk.

I am not saying not to do it ... what are the odds ... better to be judged by 200 than carried by 6 (or something)

And, I /believe/ many situations are deescalated by display of the equalizer - where no further action is needed.
Walking away is always a good outcome.

My policy is to first avoid, then flee ...
