Woah. Unless that little teeny fluffy baby was seriously threatening the man's life, why on earth would you do that? News articles say that the baby might have been rabid. They base this on the fact that the squirrel was approaching them and most squirrels avoid human contact.
Let's think about this here. The squirrel is at a school, doing what squirrels do, look for food, eat, etc. There happens to be massive amounts of food at schools. So, squirrel+school food=squirrel not afraid of people!!!!! WTF
The squirrels at central park here come right up to people to see if they have food. None of them are rabid, they just want food. Their reasoning behind it makes no sense to me unless they have some other form of evidence that the squirrel may indeed have been rabid!
EDIT: Apparently, animal control officers took care of it before setting it free again in the wild!!!!!!! Stupid man!
