Thanks for this OP.

If you want to bootstrap your way out of scenarios in the OPs, a passport card is proof of identity and citizenship.

What I do currently, is I have a smartphone with a wallet case, which has a passport card, credit card, insurance card, and a bus pass with enough fare to take a 28X[1] to the airport.

I actually just sat down to have a cortado and clean my go bag, because I had to use my mace and haven't been able to replace it.

(I the past I had a smaller "TSA friendly" messenger bag that I got at an Army Navy store plus a larger black backpack which can contain... well, pretty much anything that's legal in PA for me to put into it, but since I'm a grown adult, things like sharpies, a gerber multi tool, gum bands, an umbrella, noise cancelling headphones, and several batteries and the cables to connect them to my devices are perfectly reasonable things to carry around with me on a rainy day.)

Then, you keep that plus whatever weapons you think you need next to your bed.

I'm left handed, so usually my phone and a large knife and mace go next to the bed[0].

Then there is a locked door with a Louisville slugger next to it. Beyond that is a second door with two chains, and something else beside that one, with the walkway in between littered with hazards.

And on top of all that, I often keep a radio going so it's ambiguous if I'm home, since my landlord likes to enter my unit uninvited and not even leave a tag behind noting they were there, despite several warnings that I was perceiving their illegal behavior as threatening.

(Much like your post, I had a fire scare -- my dad claimed to know someone from the mafia who might burn my home down, and I had an outlet spark out around the same time, along with a series of odd people lurking around, some of whom still return to my home to this day despite frequent reports)

I'd love to have my passport card in a safe deposit box, but the last bank I looked into that with abused their access to the information I was looking for one.

(They said there was a waitlist, so since I thought I'd be staying long term, I just kept my passport in a safe, or separate from my passport card in case I had an extreme incident, like having my favorite bag broken open because I had to mace someone in the face, then choke them to nearly to death when they didn't take that strong hint to get away from me.)

Anyways, thanks for sharing, and if anyone has any advice on my security setup, I'm happy to take feedback.

(I'm trying to avoid making the thing on my bedside a handgun loaded with .22 hollowpoints, and the thing beside the door a shotgun loaded with buckshot small enough to not penetrate a wall and kill my neighbors if I need to fire it, but I'm very annoyed I feel a need to note this level of detail and ask for feedback, given the conversations I've had off of this site leading up to today.)

[0] The intent being to mace them, then stab them if they don't give up, then retreat to safety to call a lawyer. Not an ambulance. I'm not your caregiver. I'm not your friend. Come into my home and make me feel unsafe at night, and be prepared to die.

[1] The 28X is the route that takes you to the airport in 412, it's what I reccomend anyone who cannot abide by the rules of civil society look into rathrt https://www.portauthority.org/PAAC/apps/pdfs/28X.pdf
