Your "right of self-defense" against a military invasion (that is what it really is) of your home is possible and will go as well as a Palestinian with his little stone taking on the Israeli Genocide Force. (that is the name of their army is it not?)
In a home invasion by American Thugs (sometimes misnamed "police") the homeowner has no chance. He especially has no chance if he has women folk and children in the house to think of. The time to fight a swat team is when the city council is thinking of allowing the demon-impersonators to form on your local police force in the first place --- and, good luck with that in America.
