I would think that Marines are taught to assess the strength of the enemy, and one's own, and avoid confrontations that present poor odds.

$6k is cheap for freedom.

You're going to find it very difficult to prepare a defense from in a cell. Considering how much lawyers cost, you'd make that $6k back in mere days doing some legal research on your case.

Considering how you will compromise your defense by not taking advantage of a financial opportunity to bail out, that most people do not have, I reckon it is a foolish thing to do.

Good luck!
