Ake, six years ago and about 1000 yards from where the keyboard on which I'm typing is located, animal rights terrorists released 2210 farm-raised mink from their cages in what they charactorized as an attempt to "liberate the prisoners of bourgeois Amerika" (I remember because I didn't think the middle class could afford to wear mink, but I digress).

About 1700 of these animals were recovered the next morning, most sitting under their open cages waiting to be fed. The local DNR office (state department of natural resources) reported that at years-end 367 dead mink had been reported in the county (in a normal year, it's about 50). See if your'e smart enough to do the math yourself.

Even if one agrees that animal farming is reprehensible, "liberating" non-feral creatures only serves to change the method of death for these creatures. Your assertion that they can survive once released is a wistful fantasy whether you choose to admit it or not.
