In Oregon the laws are great!
A meth head can break in to your house and you are supposed to run.
You can only defend yourself if you feel that the intruder is actively trying to harm you.
If the intruder lives, and says you're lying and he wasn't trying to harm you, he gets to sue you for damages. Apparently, this usually goes worse for the home owner. The tweaker has nothing to lose.
The common feeling here with gun owners is that you are effectively forced to kill if you are planning on defending yourself and your family.
