"If I ask you if this path is safe, what will you answer?"

"If ask you if this path is safe, will you say {}?"

Almost anything will do, so long as it elicits a double negative:

statement about safety of path + statement about statement = actual safety of path
_____

Very, very, very old riddle:

"We carried away all that we did not catch, and all that we caught we left behind."

There is an obvious www version. Similar question, updated answer :)
