An example of how to state your opinion is provided excellently by fiddletown. He said basically the same thing, but in a much more palatable manner. I doubt anyone will criticize him.
As to your latest question, woof. My answer would be this: you are assuming his shoot will be a bad shoot. A bad shoot is a bad shoot, no matter how much training you have, and no matter how long you shot your 22 single shot. A good shoot is a good shoot, even if you bought the gun 5 minutes earlier and had to have help loading it. If the doctor was afraid for his life and the laws of his state allow him to use deadly force, then who cares if he even knows what a 22 is. If he has taken 13 Front Sight courses, and is so hyper keyed up from all his training that he sees a bad guy behind every bush and has a bad shoot, who cares how long he has been training.
You are placing the empahsis in the wrong place. Your comments here and on the abortion doctor post do not even accept the possibility that it is a good shoot. How many abortion doctors have been killed or injured? Many have. They have a right to feel threatened, especially if he has something specific. But you seem to think that he should have to wait a year before he does anything to protect himself. If he's dead it really won't matter how good he got with that little single shot, will it?
