This reminds me of the nail polish that college girls can use to test their drinks for roofies. It's well-intentioned and will obviously help when really needed but WHAT THE FUCK?!?!?! What has this country come to that we actually need these things in our society?? And plus, instead of devising ways to survive or avoid those situations, how about let's just get rid of the situation in the first place??? Focus on stopping campus rape and enforcing gun control.
