Don't care if it troubles you with 知ったことか

Grammar Explanation: Lack of interest with 知ったことか

Oyaji presented Colors with a bomb to defuse via a riddle, which led to problems for Officer Saitou. After Colors successfully defuses the bomb, Saitou tells Oyaji to stop playing bothersome games.

おやじ:: 「子供(こども)のためだ。お前(まえ)が迷惑(めいわく)被(かうむ)ろうと知(し)ったことか」; “It's for the kids. I don't care if it will cause you trouble.”; Literal: “It's for the kids. Whether you suffer trouble or not, is that something I know?”

Key Points

1知(し)ったことか dismisses responsibility

The idiom means “what do I care?” or “that is none of my concern”.
Oyaji uses it about whether Saitou is inconvenienced.

2迷惑(めいわく)被(かうむ)ろうと means even if you suffer trouble

迷惑(めいわく)被(かうむ)る means to be subjected to nuisance or trouble.
〜うと sets up a concessive “even if”.
