At IUPUI, it is not illegal to carry, but it is against the school's policies. If you are caught, you will be expelled. It's a choice you have to make. Personally, when I attended school there, I carried; typically appendix or in an ankle holster. We got enough "emergency" e-mails about people getting robbed at gunpoint walking around campus to not be able to defend myself. Not to mention cowering in a corner of a classroom with multiple doors if the next Cho is walking around shooting people is NOT my idea of a good strategy. Thankfully, I no longer spend that much of my time in a place that places such little weight on self-responsibility.
