In our Conceal Carry Law if its a good shooting the Perps family can't sue you !!

In Illinois
“In no case shall any act involving the use of force justified under this Section give rise to any claim or liability brought by or on behalf of any person acting within the definition of “aggressor” set forth in Section 7-4 of this Article, or the estate, spouse, or other family member of such a person, against the person or estate of the person using such justified force, unless the use of force involves willful or wanton misconduct.”
In other words, homeowners that are justified in using force to prevent a trespasser from entering a dwelling are also protected from any liability from the act. Neither the trespasser, nor his/her family may make any claim against the homeowner.
