That would be... interesting I think? Only if no bloodshed is needed. Stay strong you guys, I know what feels like, if anyone need urban survival advice or just confort Im here.
For now I would advice everyone of you to have a back pack of a practical size with some change of clothes, canned food and water and basic analgesics and antibiotics, one for every member of the family, all placed in the door in the event you need to get the fuck out not from civil war but from a nearby particular violent protest, massive looter gangs or whatever. But only as absolutely last resort and only if you really have a clear escape rute and the time to leave, you are far safer at home. NEVER run into a brawl or riot.
Lock the doors and check every point of entry and secure it the best you can or have the materials like furniture or planks or whatever around. The ones with iron bars and protectors on your windows are blessed under this situation (here those are standar at every home). If you have guns check them out and have the munitions ready and at hand. Secured and hidden if you have children.
In the event of tear gas comming into your housed use a handkerchief (is that th word) or any cloth soaked with vinager or even pee if you dont have it and cover your nose. Your eyes will hurt but youll be able to breathe. If a tear gas granade enter your house quickly put it unto a bucket of water but use some oven mittens or something similar because they can be dangerously hot, to the point starting fires.
Identify wich is the room that's safer in the case of a shoot out and run there or better yet have all family sleep there a few days if you feel is needed. The best room would generaly be the one with more walls between you and the street were the shooting is happening. If you have stone or concrete walls those are safer.
Buy plenty of bottled water and no perishable food. Of preference things with plenty of fat, is not the more healthy but will provide you with a good calory counting and some protein. Also of help is a propane cilinder and a portable gas cooktop. A 18kg cilinder last three months of regular cooking for a family of 3 in my experience. Have matches, dont count on electricity or running water, plan acordingly.
God, guys, I really dont wish any of you to have to pass any of that crap, my eyes are actually watered as I write this. Please stay safe.
