It looks like a case of tit-for-tat mixed with some child discipline and recreational shooting. It all started with the daughter posting a pretty bad post about her parents on her Facebook.
She then asked her father to repair her laptop and install some new software. Her father works in the IT area and discovered the post.
In addition to grounding her for her second disrespectful post, he also does some recreational shooting by putting 10 rounds into the laptop. One of the rounds was from the mother who told him to put one there for her.
He should have been wearing glasses and I doubt the bullets were exploding as he said.

I remember taking my son’s favorite toy and doing something similar many years ago as part of teaching him not to lie.
Good for this father.
