I'm not going to say BDS is tamper-proof, but there's one good thing about the stadium being tucked into an old campus surrounded by narrow streets -- it's a tough target.
The TPD has staggered vehicles to block the streets leading to the stadium, and although some of the yellow-shirt security types are just there for the party, while outside BDS before the FIU game I noticed that we have a bomb patrol group on continuous duty before games. I'm not going to put out details of it here for security reasons, but I liked what I saw.
Could someone get a device in? I suppose. Anything's possible. And if you're sitting packed in a stadium with tens of thousands of people and the big one hits, your survival strategy is pretty much to hope the primary impact wasn't in your general vicinity.
But while I'm aware of my surroundings, I won't live in fear.
