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.”

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”.
