Recovered guns?

We learned that President Obama's cabinet has a problem with what the meaning of is is. When questioned about 90% of the guns recovered in Mexico coming from the US, the spokesman admitted that "recovered" meant guns that the Mexican government actually turned over to the US government, NOT the total number of guns taken by the Mexican government.

The Mexican government only turn over guns to the US government that have US serial numbers and have a chance to be traced. By far, most of the guns in Mexico come from overseas, i.e. the AK47. So now, it all depends upon what the meaning of "recovered" is.
