As to chuckybrown's comment:
It's an interesting idea, but of course, the LL does have other clauses specifically stating that they are under no obligation to provide security or to indemify against injury or death in the Premises, and I doubt that they would modify this; however I added a provision that Tenant is allowed to provide their own "security measures." While not specifically mentioning firearms as one of the measures, I think this plus the cancelation of the weapons clause would give me some scope.I'd approach this very simply: the landlord wants a no firearms clause? It's a trade off. You say "sure, I'm ok with this. We' modify in the indemnification clause whereby the landlord exempts self-indemnification for safety issues, and accepts responsibility for the the safety and well being of the lessee and its' employees, customers, and vendors at all times".
I will give updates to the extent possible (yet another provision in the Lease would make the Lease terms confidential, so if the Lease ever gets executed, then no update).
The broader lesson here for everyone is this: check your Lease terms carefully!! As I mentioned, this was an obscure provision in a very long document and would be very easy for one to miss.
