The animal liberation front.
A group of volunteers from all backgrounds who actively free captured animals who are used for testing. Aka "lab rats". 
Discussion
I've actually begun my journey at the age of 7 or 8 when I freed circa ten lab monkeys from federal university of goiás (br) and almost got my father (professor) fired. thanks for reminding me that. the sparkle I was just needing.
i wonder what would they do w the animals afterwards
