I prefer to protect myself, rather than hope a cop is on hand when the need arises. In truth, I would rather have violent criminals bust into my house at night than a SWAT getting the wrong address. The criminals I will kill without a second thought. Being loath to shoot cops, even stupid ones who are wrongly in my house, I would most likely be shot, along with my dogs. I want people with authority over me to have be intelligent and have integrity, along with a healthy respect for life and private property. If I can’t get that, I’d rather those in authority not be armed.
Plus you can trust your own loyalties. How do you know when the cop’s going to go statist on you?
