So what's that? 15 investigators to produce each warrant? 300 investigators for 20 warrants? They are clearly not hurting for manpower.
They need to slip some of those investigators down our way in Texas and maybe do some work along the mexican border.
Over a period of a few years that doesn't surprise me. On the surface it seems high but when it comes down to executing the search warrants that averages out to 15 agents per warrant which is probably just about what you want (depending on what your up against.) Cataloging evidence can be manpower intensive too.
