We have all sorts of Penn State riot videos, photos, and first-hand accounts here, but one thing we've lacked is big-picture numbers and facts on the aftermath. Word spread throughout the night about two arrests, but police are still tracking down the official final number.
The Associated Press reports "about 100 police wearing helmets and carrying pepper spray" were on the scene. Tear gas was also used at one point, and batons were brandished. At one point, claims of police dogs broke up a large cluster of humanity. Hard to say whether police dogs were actually used as a threat, but it definitely doesn't seem any were loosed.
Expect more throughout the coming days on arrests, damage, and injuries as officials put pieces together.
