Input: Ok, so some context here. This guy I work with is part-time; he has another job during the day. He is allowed to use the staff lockerroom facility, and he was vaping (from a mod, which is known for fatty clouds) in the bathroom. He ends up setting off the fire alarms for the entire building, which is a hospital. 

I only know about this because he told me, and later showed other co-workers of ours a video of him freaking out in the stall. (He even went as far to tell our boss about it.) I asked him what happened, preparing to hear about a hefty fine or something. Apparently his cousin is a security guard there; helped him sneak out of the locker room, and into the general halls. He walked out of there, while everyone else thought it was a real fire/emergency! He told me the staff were moving patients away from the area and some people were obviously very worried.  
Authorities were called as it was not a scheduled fire drill.

Here's where I might be the asshole: this guy was laughing about the whole situation. He also kept bringing it up throughout his entire shift. I had to hear about this for 5 hours people! He made it seem like it was funny and 'totally not a big deal'. I personally can't find any humor in putting people into panic, disrupting patient care, and just wasting time, funny. I heard that the hospital caught some footage of him exiting the hall of the lockerroom, and police are asking people for information. I'm really tempted to call. So, WIBTA if I reported my dumbass co-worker?
