I don’t understand the charges against the parents. Can anyone explain?

[Pollard]

Dad gave him the gun and mom at some point that day, knew what he was going to do because she texted him; “Don’t do it”, yet never called authorities or the school.

[CottonBall]

I don’t either.

Can’t explain but the charges are

The Crumbleys were charged Friday with four counts of involuntary
manslaughter over the shooting their 15-year-old son, Ethan, is
accused of carrying out on Tuesday, when four students were killed
and seven other people were wounded at Oxford High School.

I believe they were complicit in obtaining at least one gun (via a straw purchase) for their felonious son.

Apparently the mother actually begged about it online...

[Gaffer]

I don't understand them either. I'd like to know what specific statutes they were charged with violating. I could see something contributing to the death of another person or something like that. Something substantive, like any laws on securing weapons in the home, illegally purchasing a gun as a gift to a minor, whatever...

“I don’t understand the charges against the parents. Can anyone explain?”

the prosecutors are alleging that the parents acted recklessly by providing a gun to someone they knew was a hight risk to kill someone. Reckless Homicide, also referred to as Involuntary Manslaughter.
