How did they miss a handgun on the first search? That was the thing they most wanted to find. It just seems impossibly sloppy, or there was no handgun to begin with.

Maybe they all went into the bathroom together all at once? Sometimes a man or group of men just need a handjob. If they want to collectively admit that they messed up evidence collection so they could do a circle jerk, I'll allow it. Otherwise its pretty obviously evidence tampering, which is a crime.
