Details are sketchy, but there were three kids involved. The screen was cracked and dangerous for little fingers.
Removing the cracked front panel turned out to be difficult only because the adhesive was very strong at a couple parts, mostly on the top edge by the camera. Using the iOpener helped on the other three edges, but did very little to loosen up that last edge. I had to use a scraping tool to first get under there and then to scrape the adhesive and broken shards off. This part alone took me about six hours, spread over three nights. Once that part was finally done, I cleaned out the case with a can of air, put the new part in, and had the iPad mini up and running in no time.
Apply tape to the broken screen as close to the edge as possible, but not over, since you'll need to stick something in there to wedge the glass off. The glass will break, but fortunately it doesn't shoot off everywhere. If the adhesive is strong, just keep at it and keep applying tape to any exposed cracks.
