I would suggest only engaging if you have to protect yourself or if you feel like you couldn't live with yourself if you didn't. Know that it likely means you won't be living anyway.

I would strongly suggest Chris Bird's Surviving a Mass Killer Rampage. It's a great book that follows the history of the mass-killer in the US. It breaks it down between those done by lone actors for personal reasons and those done by terrorists. It also walks you through some of the current active shooter training provided to cops and school teachers including drills and what scenarios you'll have to account for. The best part is how he looks at what you are likely to encounter vs. what you think you'll encounter.

Others have recommended Surviving a Mass Shooting by Burrese, but I haven't read it yet and have no opinion.

Target Focused Training provided a fantastic seminar on mass killers that really went well with Bird's book. It was the mental game that you should play at work or in scenarios that you think are more likely for an event to take place. The instructors were Aussie anti-terrorist guys who also do personal security contracting. At the very least, I think you should watch the video. It provides you with a great way to break down your options and also gives you something similar to a Rules of Engagement for when you need to fight and when you should run.

Finally, in force-on-force with cops, scenarios have shown that when the police show up and they see an outline of a gun, they are shooting. That even included guys holding a gun with one hand and holding their police badge in the other. They had a fraction of a second to make a decision, so they shoot. The one thing that changed it was when the gun was not immediately visible. So think covered sul position. Many of the after action reports show that police show up between 5 and 8min after it begins. So you either deal with the problem in that time and holster up, or you leave.

Not a lawyer, operator, policeman, or crossing guard. Just someone who was interested in the topic and wanted to read what I could about actual events.

Hey guys, my name is Wes. like most of us, I have had a passion for anything with Kaiju, mecha, and anime since I can remember. A few months ago I finally decided to put these passions towards something that I hope will do them justice. That’s why I wrote The Kaiju Survival Guide. This guide takes a realistic look at how to survive a Kaiju attack. It is full of details such as what Kaiju eat or even what would actually happen if a giant robot and Kaiju fought each other. The guide also includes survivor stories from some of the most devastating attacks in history.This is my first book, with many other Kaiju based ones on the way. I hope you guys enjoy it and if you want to talk to me about anything Kaiju or mecha related, you can either message me on here or follow me on twitter @mechawes for updates on the other books being released this year.

National Geographic Complete Survival Manual

It's broken up well into different environments and disasters and the layout is great. Pretty well rounded but I'm sure some of the others mentioned here are more in depth.

Here is the SERE handbook on Amazon https://www.amazon.com/Survival-Evasion-Resistance-Escape-Handbook/dp/1493700987

Do you really think that these are some super secret techniques or something? Am I misunderstanding you?

I would also suggest The Home Survivalist's Handbook. Nice basic survival advice for those living in the city.

Walden by Thoreau. - much more of a meditative journal than a day to day 'how I did it.'

'My Side of the Mountain.' by Jean Craighead George - kids book, and doesn't describe many (or any) failures, but interesting.


Look for the Armed Services emergency survival manuals.

Hopefully he's not camping at a campground and you're freaking out about it.

Like what others have said, this is /r/bugout not /r/prepping or /r/collapse. That being said, While it is important to have gear that is ready and capable for bugging out, first of all, where are you going? Is this a designated area like a cottage or vacation home? Or are you just going to walk as far away from the affected area?

Another thing to consider, is try focusing on skills rather than gear. While gear can magnify your capabilities, it won't do you jack squat if you don't know how to effectively use those items, or in the event that the item is lost, stolen, broken, etc. the ability to complete a task without said gear.

For starting out I'd recommend these books:

Build the Perfect Bug Out Bag: Your 72-Hour Disaster Survival Kit

Bug Out: The Complete Plan for Escaping a Catastrophic Disaster Before It's Too Lat

Car Emergency Kit:

• Fix-a-flat can
  
• Reflectors
  
• Full roll of Duct tape
  
• Full roll of Toilet Paper
  
• Lighter
  
• Heat-reflective blanket (bonus if highly visually reflective)
  
• 1 Liter of water
  
• Shovel/Spade (foldable is best)
  
• Multi-tool
  
• 50' Rope
  
• Granola Bars (rotate them out occasionally, of course)
  
• Book on how to survive in the woods

Your urine actually dehydrates you more than saving you because your body has to reprocess all of the toxins that you release. There is a a way to cleanse it though. You have to boil your urine and then pour it through rocks and sand and than repeat that a couple of times. Read this in a book some one bought my it is called

I'm not sure that it's still classified by the fact that it's all over the web and in print from Amazon.

That might make your question moot. But stealing classified information is still illegal. However if you're a "legitimate" news service you can, "in theory" publish even stolen classified information that you are given. It might be a good idea to have a lot of money to pay lawyers, though.

I'm not willing to go into politics on this sub, especially current politics, but the historical example was the "pentagon papers" and !w has a decent overview if you're unfamiliar with the case.
