Wow. I'm all for defending Hearth and Home and would willingly do everything I can in the event of a home invasion by ANY entity, but you can damn well bet the odds are stacked against you. If you were to fire upon or kill an invading SWAT team you better be ready for "Suicide by police". I'm not saying don't do what you have to, I'm just saying you better be committed because it would not be a friendly understanding environment. We've all seen the gung-ho tactics on youtube video and there are so many publicized cases of abuses of police power, but in the heat of the moment, they have the power and it's only in retrospect that watchdog groups are able to to bring some kind of justice to the families of the assaulted. Don't know what a good solution would be, but I hope I survive if I have to make that decision myself. Just my .02. Oh, first post on this site btw.
