quis

Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Ut enim ad minima veniam, quis nostrum exercitationem ullam corporis suscipit laboriosam, nisi ut aliquid ex ea commodi consequatur?

The tragic thing about core human societal issues like this the same issues keep coming back, again and again- Quis custodiet ipsos custodes?

But this is a general problem of Quis custodiet ipsos custodes?

Well, at least we now know the answer to Quis custodiet ipsos custodes?

Ultimately, quis custodiet ipsos custodes?

The phrasing is very similar to "quis custodiet custodies" - who watches the watchmen - which is a very well known phrase.

"Quis crespit crespulum" might make a nice personal slogan — depending on what it means.

Not sure, but maybe: "Quis crepuit crepulum." Who rattles the one/thing rattling?

I feel like that should be made into a latin phrase like "Quis custodiet ipsos custodes?" Someone better versed in Latin may need to double check this: "Quis prosequiet ipsos prosecutores?"
