Yep, jail time seems very unlikely since the Detective made a comment to the fact it was okay to protect your home against unwanted visitors so cops are on her side with a written statement.

Also, her actions were not unfounded; she was on the phone with dispatch for 21 minutes, meaning she was looking solutions, not some killing rampage. The fact she didn't shoot the second guy (because he gave himself up) shows she only used the absolute necessary force to protect herself and child, nothing more.

Good for her.
