I suppose we don’t know, what we don’t know. But it would certainly appear that these open air stadiums have certains risks...
But hey, let’s hassle a nun about per possible involvement as a terrorist before boarding an airplane instead...
Not just stadiums but any gathering of innocent potential victims. Just this week, a Honduran in Miami tried to blow up Dolphin Mall. Made his ISIS videos and statements of support but Local 10 news/media already has stories out that there is “No connection to international terrorist”. He was on his way with the “fake” bomb supplied by FBI informant, tried to arm it and place it in the food court.
