Butler University is not firearms-friendly, but they barely have a policy on it. CC should not be an issue at all.
From a legal standpoint, just be aware there is a school at the corner of Boulevard and 49th and over at Illinois and 46th. Don't park there.
Park in the garage, or on campus somewhere, if you can. Locals don't care much for visitors parking in front of their homes. Smash-n-grabs are also not uncommon along the streets during events.
