PETA are annoying, but you can ignore them. It's the Animal Liberation Terrorists you have to worry about, but understandably there aren't many of them around and they aren't exactly very smart, so most of them get caught very easily.
I'm just glad I never did research in the US. In Australia, we haven't had such nut-bags protesting outside our research buildings (at least, not very often. You'll see a few in summer, but campus security asks them to get the hell out pretty quickly, and all our doors have pretty good locks. Plus, we also tend to store most of our animals offsite or in secure rooms, so even if they smashed the windows they wouldn't be able to get to the animals out - so they have no reason to invade labs since they couldn't "save" their precious "captives" - as if a mouse has the intellectual capacity to even comprehend what is happening to it or it's "captivity". We give the mice/rats food and water and a (mostly) painless death. They only live 2 years anyway.
And if any of these terrorist lunatics did break in, we have some pretty nasty chemicals with which to defend ourselves if necessary.
