well link the thing is when you have undead corpses running around eating people a few armed civilians taking over a wallmart is going to be the least of there worries so dont worry about cops. When it happens it will simply be those with guns and zombies (take not the "people" without guns will be zombies).
Okay, duly noted.
and flame throwers? honestly when is the last time you saw one. And if you had a choice at a weapon that burns things at close range or a weapon that explodes them at vast distances, which one would you choose. IMO the farther away it is when i kill it the better.
Improvisation, my good man.
I'd rather have the guns, but if you need to go RE-style and burn them so they don't reanimate, flamethrowers would be handy for close-in combat or clearing the field of the dead ones.
Five days, hmm? I'll have to make a detailed plan for this.
There's a big, three-story brick high school near me--one of the largest in the state--so I'm thinking I could hole up there with supplies. There's a hardware store nearby, too, so I could load up on supplies from there and bunker down in the school with others. It's all brick and stone, so it should hold up pretty well. The roof would make for an excellent sniper post as well--there's plenty of cover and you have a clear shot for a great distance.
Day one would probably be for recruitment and getting supplies the "conventional" way--getting guns and stuff, getting lumber and all of that, and food. That and starting to work on fortifying the exterior entrances of the building. We'd probably want to strongly fortify doors, windows (on all three levels, not just the first--I'm going to assume the zombies are smart enough to climb and stack up if necessary). I'd also pour some concrete in front of doorways with too much glass and do some bricks there as well (I'd be having my recruits help me with this, obviously). Storage of food would be important, so freezers/refrigerators would be brought in, as would airtight containers and multiple generators.
Day two would be more "unconventional" methods, like stealing stuff that we really need (more guns, ammo, better weapons, more food, etc.). I'd start by closing the security gates in nearly every area (with the exception of maybe one path that leads to cafeteria, bathrooms, and one stairwell. Then it's time to pour some more concrete and brick up the areas behind the gates. Oh, and I'd use the elevators to transport the vending machines upstairs to the second or third level--I wouldn't just smash them because I'd want to keep the drinks in them cold as long as possible. Priority would be securing all entrances not yet completed and reinforcing those that were already secured. Those routes deemed crucial (cafeteria/food storage/bathrooms) will be reinforced at least two times. Certain hallways will be sealed with bricks to give the appearance that there is nothing but a wall there--there are several locations ideal for this. Stairwells will be sealed, with the exception of the one route. All windows will be boarded from the outside if feasible, and bricked up from the inside.
Day three would involve further reinforcement of the crucial areas, going to the roof to build solid concrete/brick structures around entrances that lead into the building (and adding the thickest, sturdiest doors available, be they steel or anything else). Only necessary rooftop entrances will be given this treatment; the rest will be sealed as thoroughly as possible so they cannot be opened. A few classrooms branching off of the "crucial" route will have been left unsealed (with the exception of the windows). These will be fortified and will contain weapons caches and stores of food, so any single one can offer a strong defense on its own. Ceilings will be fortified as best as possible, whether through sealing holes or any other method. Most likely method would be strong plywood.
Days four and five would be the completion of these projects and further fortifications as needed. There can never be too much reinforcement! Enough building supplies will have been looted to keep us busy and leave us with a supply of repair materials.
