The case of the mistaken employees (Hinkle and some else was it) is well-known, as is the fact that PETA euthanizes a lot of animals who are not terminally ill etc. This has garnered a lot of criticism of PETA from inside the AR community - from those who actually give a **** about the situation, unlike Berman & co.
CCF pointing it out, even as a matter of internal consistency, shows no decency as usual, since they don't have any qualms with the pet industry causing this problem in the first place. Basically, society - because of the attitudes that CCF, Penn & Teller and others represent - dumps a giant problem at the animal organizations' feet and then has the audacity to complain how PETA tries to solve it.
