It would be something like:

"It doesn't matter..." (but it cannot be properly completed without a context).

I'd translate Lampada's example ("Да мало ли в чём он был замешан.") as:

"It doesn't matter what he was involved in"
Да, я согласна, потому что данный оборот указывает на присутствие некоторого недовольства у говорящего.
Moreover, Mr Ожегов also agrees with me
