NEVER move the body. Modern forensics can tell if the body was moved at any point after it came to rest.
Even if it really was a good shoot, you will then go to jail for obstruction, falsification of evidence, tampering with evidence, and will be under suspicion of murder because of the above.
If you live somewhere with restrictive self-defense rules and it’s important to you, don’t think about moving the body. Think about moving somewhere else that doesn’t deny your right to self defense instead.
He had a screwdriver in his hand. That could easily be construed as a deadly weapon. She was “in fear for her life”.
Heck, the police have shot and killer innocent bystanders presenting less of a threat and gotten away with it.
“Moving the body” was hyperbole! Better I should have said “lure him indoors and then shoot him”. My point is that most jurisdictions do not allow you to use deadly force to protect property — especially remote property.
Everyone also should realize that there are a lot of bad lawyers out there.
