It's hard to know what actually happened in this particular situation because no context is given and we don't know what the circumstances were, so I wouldn't put any stock into this particular post/situation...HOWEVER:
PETA is not a law-enforcement agency, and there is no way at all they could enter someone's home and remove/take any pets without the owner's permission to first enter the house, and then to take their pets...so that part is just not true...Just as the Humane Society, the SPCA, and any other animal rescue group would have to do,
PETA would also have to go to official law-enforcement and have them go to a person's home if they suspect animal abuse or neglect, and even law-enforcement agencies in most countries/states, such as local or state police, would still have to have a Court-Order from a Judge in order to enter a person's home and forcibly remove an animal.
NOT EVEN LOCAL, STATE, OR FEDERAL POLICE CAN ENTER A PERSON'S HOME AND REMOVE ANY ANIMALS/LIVING CREATURES WITHOUT THE OWNER'S PERMISSION UNLESS THEY HAVE A COURT-ORDER SIGNED BY A JUDGE AND NOTARIZED. That's just how it works. So any tales of PETA going to a private home or a public business and LEGALLY entering the home without the owner's permission and LEGALLY taking a pet from the home, even if there is obvious abuse or neglect, are just that, they are tales and exaggerations, and you're not getting the whole story...Now if PETA took evidence of neglect and/or abuse of a person's pet to a Judge, they had a hearing, and the Judge signed a Court-Order to have the pet removed and custody signed-over to PETA, then PETA could go to the home, present the Court-Order to the owner, and if the owner didn't willingly let PETA into their home or hand-over their pet to PETA, then they usually call local law-enforcement to come to the home and "enforce the Court Order"...
****As far as PETA as an organization goes, they unfortunately mean well and want to do good for the welfare of all animals and pets, but they are more than willing to break the law and do not only illegal things but also immoral, unethical, and a lot of the time destructive and/or violent things to get the end-result that they want; PETA members are very often arrested, convicted, and go to prison on a regular basis for doing anything and everything they feel necessary to achieve their goals...And as already stated, they long-ago very much became a "militant" group...When PETA members started destroying property and causing physical, bodily harm to people in-order to either rescue animals, or more-so anymore just to simply "punish" a person or company that they feel deserves to punished for hurting or killing animals, I found it very difficult to understand the hypocrisy of their actions...Why is it okay to hurt and potentially kill human beings in order to save animals?
Individual PETA members started going-rogue and just getting totally out of control back in the late 80's forward, and it's a shame because they actually do a lot of good as an organization, they really do, and on a regular, daily basis. Unfortunately the illegal, immoral, and unethical behaviors of a lot of their members always overshadows any and all good that PETA as an animal-welfare organization regularly does.
