Lots of views and all are important.
Taliv is right, we don't talk about upgrading our home defenses - from the perspective of what you actually can do to the home itself. It's why I only indulge in noting that most discussions go directly to handling the complete failure to do anything at all and resorting to a firearm. The nature of a gun (only) forum forces us to consider what to do when a massive failure to prepare beforehand presents itself.
Those of us who were trained Combat Arms have a completely different perspective, all of it based on what you do to prevent self inflicted ignorance resulting in exactly what you were tasked to prevent.
So, focusing on the gun only and why you have it to protect your home, we see a variety of answers on how that needs to be addressed. It does depend on your local political climate and how the Authority Having Jurisdiction handles cases. The point is - you bought the gun and you DO intend to use it in an extreme situation. You buy ammo and practice. You do give consideration to when and how it might be used. You are not one of those who plans "to wake up with a knife at your throat," probably one of the more hilarious threats tossed out by posters.
Since it's High Road, you'll call the cops, they will arrive, proceed with clearing the house if they think it's necessary, maybe even cuff you.(We don't discuss hiding the body.
) If you haven't looked into how YOUR jurisdiction handles it, you need to know - things like answering the door and opening it with your gun still in your hand might be expected by a seasoned LEO but the night shift usually gets rookies - who only know shots were fired and there are people armed doing it.
It's going to be a stressful and complicated time, more so AFTER the event.
Your gun is going out the door in police possession and if you intend to still defend your home then the long term plan needs to address it. That may be a quarterly discussion for some, but if it's getting buried in S&T then it's not being addressed to the larger forum population. Most of us buy guns for protection - there might be a few who wouldn't, that question was asked. Since most of us will, it's not getting discussed where the majority see it.
Since it's actually happening and does happen, it's a lot more fact based than some speculative scenario where the cops are going door to door confiscating them. Nope, they are right there IN YOUR HOME confiscating guns. As attested to by the posters above.
What started my thinking on this was a thread elsewhere and a discussion on the value of the gun to be used. It ranged from "use a cheap gun" to "it's a gun and it did its purpose, regardless of value." My concern is that if you do use it - kiss it goodbye for a long time. You still need a backup plan - which a lot of people admit on forums by addressing a second magazine, a second BUG, a trunk gun in the vehicle. If, in the worst case situation the police seize every gun they can expeditiously find in your home, will you be completely disarmed, or not?
How are you addressing that back up plan? Once again we are led to thinking about how to keep guns in the house that can be accessed after the incident. It's nice if the police don't take them, but can you absolutely guarantee that will continue to be the policy in the future?
I see residents of CA pondering that problem as we speak. NYC is already a defeat.
