The court says this is ok. So, in the middle of the night when no one can see, strangers crash into your home. You are an American citizen so they know you might be armed, so they stage an armed assault. This is to insure no one gets hurt except maybe you.
When you hear the noise, and you will, this is meant to intimidate, what will you do? Obviously when your door is smashed down, smoke grenades tossed about, shouting and chaos jolting you out of a sound sleep, you would naturally assume this is a normal and acceptable occurrence, get out of bed, put your arms behind your back, and await your fate. Wouldn't ever worry about your wife and daughter, no chance of their getting hurt. Surrender is always a mans first choice.
Maybe in your startled waking you misunderstand what is happening. You grab the shotgun you have kept for years on the remote chance of home invasion. A man rushes toward you so you raise your gun and fire. Maybe the invader is hurt, maybe his armor and helmet protect him. Probably more then your PJs do when his cohorts defend themselves with their automatic weapons. Maybe some of your family will survive.
But this could never happen. There is absolutely no chance that they got the wrong address. That an informant, so save his ass, made up an address and it was yours. Maybe your doctor prescribed too many pills for your cancer pain. You might have made a suspicious cash transaction, any large-ish amount. Did you make any overseas calls? Visit any radical websites? Wear a seditious T-shirt? Bumper sticker? Protest? Write a blog?
If you survive what will happen to you? Will a judge set your bail? Can you have a lawyer? Will you be sent to a military jail and face a tribunal? Maybe a secret court that doesn't even tell you your crime. Will you be encouraged to confess while being "stressed"? Will a secret plane take you to a foreign place where people you can't even speak to do horrendous atrocities to your body, until you beg for death? Will they torture your wife and child before your lidless eyes?
Oh yea, I remember voting for that....?
