You can't use TikTok on the University of Texas Wi-Fi. Concealed guns on campus still allowed.

@drewharwell I assume concealed guns are okay because there's never been a gun related incident on campus.
@lloydian @drewharwell I’d guess that the vast majority don’t get that your post is ironic, and even fewer know why.
@Gregnee @drewharwell I attended UT. I remember going into the admin building and seeing the doorway that led to the tower. Wondering about the view, I asked someone if I could go up. That was the day I found out.
@lloydian @drewharwell I knew of the shooting before I started at UT. Watched a documentary about it later.
@lloydian @drewharwell I have a vague memory of touring the observation deck at some point, which I’m pretty sure was a guided/scheduled thing. I couldn’t think of a time after I started college that I would have done that, but I think it was during a weekend recruiting event they held for smart/NMS kids.
