I wish that were true, but our legal system is so broken it almost works the other way. The defendant of an injury civil suit can easily suffer more in time and money than a convicted murderer.
For example, suppose the rubber pellets hit this burglar in the eye, leaving him blind. A lawyer jumps on the case on a contingency fee basis. Now the homeowner will spend years of his life in court, paying his lawyer, and trying to settle the claim. This homeowner could easily waste two years on defense, then spend the rest of his life paying off some $3 million settlement to the plaintiff. Now that's serious.
Also, remember a jury usually does NOT look at these injury cases in terms of justice, but as a "problem to be solved". Here, they'd see a helpless man disabled for life. They see a wealthy homeowner. Solution: have the homeowner pay his bills.
Personally I'd judge this homeowner's actions as legal, but somewhat foolish. Investigating outside your house with a long gun is dubious from a lawyer and safety perspective. Suppose a LEO had been tracking this burglar and met him in the breezeway - the interaction might not go well. The account also does not mention any attempt to seek verbal compliance ("Get out of my house!", "Show me your hands!", etc).
To be clear, I support this homeowner overall, just would not recommend anyone else take the same actions.
Point taken, but I am confident that I could hit an intruder's body and not his eye, and figure that if damages amount to personal injury and not wrongful death, that still would be preferable. Just the prospect of doing time for murder, being legally dead, doing a life sentence, etc, sets my mind reeling.
Just because that side has a civil prosecuting attorney does not preclude my retaining a decent civil defense attorney, too. At least "the people," are not breathing down one's neck that way.
I will admit, however, that a dead man's not being able to tell any tales is a good point, but lethal force, it seems to me... it seems that only cops ever get away with that. Look at the case with George Zimmerman. What an ordeal that is.
