Not a home but if you were a bank and a 17 year old walked into the bank, talked to someone and was able to walk out with a fat stack of cash i think the insurance company would have to reconsider your policy.

Absolutely any 17 year old can walk into a bank/shop and get out with cash. Preferably armed and not alone.

The challenge is to get out and never be caught.

According to a family friend who used to work bank robberies for the FBI, it's very easy to get away with one bank robbery. It's the compounding evidence when you commit more that gets you. Of course, that was a couple decades ago. I'm sure better surveillance technology has shifted that balance some.

Not home security, but I'm of the opinion this should apply for businesses and public places in some case. For instance, I usually carry a gun on me. If I go into the court house or a concert venue I'm prohibited from doing that. IMO they have now assumed a level of liability to provide a reasonable level of effective security and they're negligent if they don't and I'm injured or kill because of a mass shooting anyway because they didn't enforce their own policies.

Speaking of guns, it's actually also not unheard of for people to be partly responsible for crimes committed with guns that were stolen from them, even in their home. You have something dangerous, like a network that has become a de facto platform for government officials, then yeah: you have a responsibility to take reasonable preventative measures too.

I find it odd that you think a gun protects you in public. Its always seemed to me like you are more likely to be shot if you're carrying a gun, because an armed criminal now has to shoot you first if they want to ensure that they are not shot themselves. If you are unarmed they can simply threaten to shoot you and need not actually shoot.

I guess in the US thee are so many guns that perhaps criminals will just assume that you're armed anyway. But IMO that only makes the case for gun control stronger. Because the most effective way to change that attitude would be to dramtically decrease the number of guns in circulation.

The gun is well concealed and I'm an accomplished competitive shooter - no I'm not concerned about that.

It isn't fair to compare to home security. If someone breaks into my home, only my belongings are lost.

If someone breaks into Twitter, user data is compromised. It's not just the business that pays a price.
