Oh yeah?
A man comes to my home and threatens me with a club? Castle Doctrine invoked!
Turn it around: You go to a man's home with a club and threaten him. You expect to be invited in for tea and crumpits? Don't be on it. Castle Doctrine invoked! You won't know what hit you.
LESSON #1: Do not threaten anyone with violence--especially in his/her home or place of business. Castle Doctrine!
LESSON #2: Relax. You can sleep peacefully at night knowing that your children are safe in their beds because violent criminals who would harm--or kill!--them are deterred by the Castle Doctrine--and that you are safe from harm if you stop them should they try!
>> You can sleep peacefully ... your children are safe in their beds ...
See the link below for a fascinating discussion on this (the original quote is often attributed to George Orwell). And be sure to look up the complete Rudyard Kipling brilliant “Tommy” poem.
