The leader of the arson attempt had received money from PETA to use for his legal defense, although PETA did not organize that particular attack itself.
So, I'm guessing the people who are members of PETA are vegetarians; they eat only fruits and vegetables because, of course, they believe that animals should not be eaten.
So a PETA member might go into the laboratory pretending – acting as if she were a scientist, but really taking photographs and collecting information about the laboratory.
I've always loved this time of year - Spiced pumpkin lattes, bringing my winter furs out, then bringing my winter furs to the dry cleaner's to get the red peta paint out.
