Debate Club

The basic sequence of events:

1. Boy, age 15, confesses to mother that he'd had "inappropriate contact" with sister, age 3.
2. Mother calls Father, and tells him, "[...T]this isn't something you sweep under the rug."
3. Father shows up at Mother's home with gun, beats Boy over Mother's protests, then marches him outside, and shoots him dead.

Cue random online debate, where people toss out whatever's on their minds.

But this raises an interesting question. How do you have a public debate over something like this? What does "a public debate" even mean in this circumstance?
