Maybe I have the wrong kind of attitude to be living in the country. My shed does not contain anything that's worth killing someone over. If someone's breaking into my shed and a shouted "Oi !" and a flash in the eyes with a torch isn't enough to dissuade someone from stealing something or anything from my shed then they're welcome to the contents of my shed.
My garage contains a couple of classic cars, a couple of thousand pounds worth of tools, a few hundreds of pounds worth of bikes and various other things and whilst I would much prefer that someone didn't break into my garage and steal it, it still isn't worth me taking a life over.
Now the standard response is that how do I know that they won't go on to break into my house and go on to kill and rape my wife so why shouldn't I engage them with deadly force. My response is that kind of thing is almost unheard of in this country (and presumably is vanishingly rare in any first world country).
Quite a lot of decisions are made between observing intruders and issuing deadly force.
That should be the point of this thread.
You can challenge the actions of others without getting even half way to deadly force.
I will ALWAYS check it out so long as I have the ability to gain cover (not just concealment) quickly, and the ability to retreat, AND the ability to dissuade an attack with non-lethal force.
Why? Because odds matter not, if it can happen your plan should account for it happening. What happens if the person breaking in is in distress, perhaps choking on something, or in diabetic shock, it has happened before, it will happen again. I might save a life, or what happens if it is the neighbors kids and I can help my neighbors be able to know they need to do something to intervene in there wayward youth . . . it takes a village after all (seriously, not tongue in cheek).
IMHO assuming anything without primary data is a mistake, and should only be done when the risk is acceptable (I guess this is where we all disagree on what is acceptable risk, and what mitigates that risk). This is true in all situations for ever to the ends of days no matter the topic.
Knowledge matters in decision making, and if you are ill prepared and thus fearful of what could happen and either act, or do not act when it is needed based on a lack of knowledge the answer is to get that knowledge, not to remain apathetic in hopes that everything will work out ok.
TL;DR
Tactics based on primary data should dictate what decisions are made, not fear.(ie the rate of occurrence might make you feel safe, but knowledge of risk and tactics is more important than how you feel in such a situation.)
